As long as you\u2019re not involved in them, petty arguments can be entertaining. Whether it\u2019s two co-workers bickering about communal fridge leftovers or reality television stars drunkenly brawling over perceived insults, watching other people feud is a guilty pleasure that we\u2019ve all participated in.\u00a0Much like everything it does, Hollywood takes personal feuds to the next level. https:\/\/www.youtube.com\/watch?vDye84qW_4V8 No matter if it\u2019s sisters trying to outshine each other or friends sleeping with each other\u2019s husbands, tinsel town is home to some of the best squabbles around. Let\u2019s delve into some of the nastiest, meanest, pettiest feuds in Hollywood history.\u00a0 RELATED: A Closer Look At Olivia De Havilland\u2019s Ugly Feud With Sister Joan Fontaine 1. Bette Davis vs Joan Crawford Bette Davis (left) and Joan Crawford (right), Everett Collection To answer the classic 1980s query \u201cwhere\u2019s the beef?\u201d\u2014 right here, sandwiched between these two golden age Hollywood stars. The feud started way back in 1933 when the announcement of Davis\u2019 breakout Hollywood movie was relegated to the back pages after Crawford publicized her divorce the same day. The movie, Ex-Lady, failed and Davis forever blamed her fellow actress. And if you think that\u2019s petty, just wait. In 1935 Crawford married the man that Davis secretly loved, and a year later mocked Davis\u2019 plain navy blue Oscars dress to her face by sneering, \u201cDear Bette, what a lovely frock!\u201d\u00a0 WHAT EVER HAPPENED TO BABY JANE?, from left, Joan Crawford, Bette Davis, 1962, Everett Collection The two women continued to hate each other, and Davis struck back in 1952 when she starred in The Star, a story about a washed-up Hollywood actress desperately clinging to fame that was a thinly veiled depiction of Crawford. The two then strangely agreed to both appear in What Ever Happened to Baby Jane? in 1962, a traumatizing experience that led to outbursts of physical violence from both parties. Death couldn\u2019t even put a damper on this feud - when told of Crawford\u2019s death in 1977 Davis replied, \u201cYou should never say bad things about the dead. Joan Crawford is dead. Good.\u201d\u00a0 2. Dean Martin vs Jerry Lewis Everett Collection Dean Martin and Jerry Lewis were a show biz dream team. One was a sultry crooner with the voice of melted butter, while the other was a zany comedic genius who could make anyone laugh. The two teamed up in 1945, and their career soon exploded. By 1951 they were the highest-paid act in show business, but all was not well in paradise. Martin was becoming increasingly frustrated that Lewis was seen as the brains behind the duo, while he was relegated to boring romantic leads in their movies. This tension came to a head after a Look magazine story about the two cropped Martin off the cover entirely.\u00a0 THAT'S MY BOY, from left, Dean Martin, Jerry Lewis, 1951, Everett Collection In a fight, Martin told Lewis that he was \u201cnothing but a f\u2019ing dollar sign to me,\u201d the duo broke up, and they didn\u2019t speak for an astounding 20 years. Fortunately, this story has a happy ending. In 1976 Frank Sinatra organized a surprise appearance by Martin on Lewis\u2019 annual Labor Day telethon. The two embraced, began to banter, and their old chemistry immediately returned. After their reunion, Lewis and Martin talked every day, and Lewis later stated about their 20 year period of silence that, \u201cthe stupidity of that, I cannot expound on.\u201d\u00a0 3. Olivia de Havilland vs Joan Fontaine Everett Collection If blood is thicker than water then Olivia de Havilland and Joan Fontaine must have been on some crazy blood thinners, because this sibling rivalry was intense. The pair rose to fame at the end of the \u201830s, with Olivia starring in Gone With the Wind and Joan having her own breakout success in Rebecca. You would think the sisters would be happy for each other, but they were anything but. Joan claimed she was turned down for the role in Gone With The Wind because she was too stylish, at which point she suggested her sister as a replacement.\u00a0 Olivia de Havilland and her sister, Joan Fontaine, 1948, reception to honor Ralph Richardson making his Hollywood debut in THE HEIRESS. Everett Collection Then in 1942, both women were nominated for the best actress Oscar. Olivia was favored, but Joan pulled the upset, and Olivia refused to congratulate her younger sister - a scene that played out in reverse five years later when Olivia won her first statue. And there was no late life reconciliation for the two, either. In 1978 Joan said about her sister, \u201cI got married first, got an Academy Award first, had a child first. If I die first she\u2019ll be furious.\u201d\u00a0 4. Gwyneth Paltrow vs Martha Stewart Everett Collection \u00a0In 2014 Paltrow was several years into running her extremely popular lifestyle business Goop when Stewart told reporters exactly what she thought of the endeavor. \u201cShe\u2019s a movie star. If she were confident in her acting she wouldn\u2019t be trying to be Martha Stewart.\u201d Shots fired. And Stewart didn\u2019t stop there. After Paltrow announced her \u201cconscious uncoupling\u201d from husband Chris Martin, Stewart published a pie recipe entitled \u201cConscious Coupling\u201d in her magazine. Which is awesomely petty. Paltrow wasn\u2019t one to take this lying down, however, and soon posted her own recipe for \u201cjailbird cake,\u201d a thinly veiled reference to Stewart\u2019s time behind bars.\u00a0 If only every rivalry played out in the realm of baked goods, this world would be way more delicious. And the two still haven\u2019t squashed the beef. After Paltrow\u2019s candle called, \u201cThis Candle Smells Like My Vagina,\u201d sold out immediately in 2020, Stewart stated that, \u201cI don\u2019t think that\u2019s America. I think it\u2019s a lot of guys who are horny.\u201d\u00a0 5. Frank Sinatra vs Shelley Winters Everett Collection In the early 50s, Shelley Winters was used to getting any man she wanted. Her conquests were both many and legendary. In addition to bedding Errol Flynn and Marlon Brando, Winters claims to have made love with Sean Connery on a train the whole way from Liverpool to London. But her charms were wasted on her co-star in the 1952 film Meet Danny Wilson.\u00a0 MEET DANNY WILSON, from left: Frank Sinatra, Shelley Winters, 1951, Everett Collection Ol\u2019 blue eyes himself, Frank Sinatra, and Winters took an immediate dislike to each other. After a tension-filled day on set Sinatra reportedly called Winters, \u201cthat bow-legged b---- of a Brooklyn blonde,\u201d after which she \u201cscreamed like a fishwife\u201d and punched him in the face. Not sure exactly what a fishwife\u2019s scream sounds like, but I\u2019d imagine it\u2019s terrifying. In a later interview Winters referred to Sinatra as \u201ca skinny, no talent, stupid, Hoboken bastard.\u201d Their film was a flop, and unsurprisingly the two never worked together again.\u00a0 6. Elizabeth Taylor vs Debbie Reynolds Everett Collection Hollywood royals Elizabeth Taylor and Debbie Reynolds met when they were teenagers coming up in the film industry and soon became fast friends. Reynolds was even matron of honor at Taylor\u2019s third wedding, to producer Mike Todd. So it was only natural that when Todd died in a plane crash only a year later that Taylor\u2019s close friend and Reynolds\u2019 husband Eric Fisher rushed to comfort the grief-stricken star. Comfort her, that is, \u201cwith his penis\u201d as Reynolds\u2019 daughter Carrie Fisher so eloquently wrote. Eric Fisher soon abandoned Reynolds and their two young children to marry Taylor, an event that for some reason ended the two actresses\u2019 friendship.\u00a0 Elizabeth Taylor, Eddie Fisher, Debbie Reynolds at the Tropicana Hotel in Las Vegas, June 19, 1958, Everett Collection All was not lost, however, and 7 years later when Reynolds and Taylor discovered that they were on the same cruise together, the two decided to have dinner and mend some fences - a reconciliation probably helped by the fact that Taylor had dumped Fisher for Richard Burton. They even starred together in the 2001 movie These Old Broads, although if I were you I\u2019d definitely skip it.\u00a0 7. Vivian Vance vs William Frawley Everett Collection Famous as the best friends of America\u2019s sweethearts Lucy and Ricky Ricardo, it\u2019s a testament to the acting chops of Vance and Frawley that everyone who tuned into I Love Lucy saw them as a loving couple. Because the two hated each other from the moment they met. Vance was outraged that someone 22 years older than her had been cast as her husband, stating quote, \u201cNo one will ever believe I\u2019m married to that old coot.\u201d When Frawley got wind of her comments he was incensed and began to openly refer to her as \u201cthat b----\u201d on set.\u00a0 I LOVE LUCY, 'I Love Lucy Christmas Special,' from left, William Frawley, Desi Arnaz, Lucille Ball, Vivian Vance, season 6, episode 11, aired December 24, 1956. Everett Collection The two were forced to share the small screen for nine years, which was more than enough time for Vance. Despite its almost guaranteed success, she nixed the idea of a Lucy spinoff about the duo during pre-production, refusing to ever work with Frawley again. The two never buried the hatchet - upon hearing of Frawley\u2019s death in 1966 Vance reportedly exclaimed, \u201cChampagne for everyone!\u201d Well, there you have \u2018em, some of the juiciest feuds in Hollywood history.
