by Kristen HarrisBuzzFeedBuzzFeed Staff A Hollywood marriage isn't for the faint of heart. Actors often have attractive costars pretending to be in love with them for the camera or adoring fans swooning at their feet. So, when you hear about your favorite actor having an affair, the reaction is often disappointed but not surprised. This certainly isn't a new phenomenon - it's a tale as old as Tinseltown itself. Here are 16 wild Old Hollywood cheating scandals: Content warning: This post mentions domestic violence, alcoholism, and mental health issues. 1. In 1916, 19-year-old Marion Davies was performing in Ziegfeld Follies on Broadway when she first crossed paths with newspaper mogul William Randolph Hearst, who was 34 years older and married to Millicent Willson. Marion and William had a 35-year-long affair because legal divorce didn't feel like an option to him. Bettmann / Bettmann Archive / Via Getty Leaving Millicent in New York, William whisked Marion off to Hearst Castle in California. The new couple became known for their star-studded parties. William already had five sons with Millicent, but three years into the affair, he and Marion welcomed a daughter named Patricia. He also helped Marion build her Hollywood career by financing many of her films and founding production companies. However, the financial support wasn't one-sided. In the '30s, she gave him a million dollars to save his business. In return for her generosity, he reportedly left her the company in his will after his death in 1951. Bettmann / Bettmann Archive / Via Getty Marion told Time, "I would do anything in the world to avoid hurting the boys [Hearst's sons]. After all, they're half of W.R. I'm not the fighting type, but I don't believe in disregarding W.R.'s wishes. He had a reason for having the agreement drawn up. He thought I was the one who understood best what his policies and principles were and that I could see to it that his ideas were carried out... Gosh, I thought I'd have a peaceful time in my old age [51]. Now look at the spot I'm in!" There's one enduring mystery surrounding the longtime couple. According to a longstanding rumor, while aboard his yacht in 1924, William - believing Charlie Chaplin was having an affair with Marion - allegedly tried to shoot Charlie but hit film mogul Thomas H. Ince instead. The incident was allegedly witnessed by Louella Parsons, a famous gossip columnist, who traded her silence for a lifelong contract. At the time, reports said Thomas died from acute indigestion, but the legend persists. It inspired the 2001 movie The Cat's Meow. (C)Lions Gate/Courtesy Everett Collection 2. In 1948, Ingrid Bergman was married to neurosurgeon Petter Lindström when she began an affair with director Roberto Rossellini on the set of the 1950 film Stromboli. Ingrid conceived a child, and she gave birth to their son (also named Roberto) a few short days before her divorce was finalized. Ullstein Bild Dtl. / ullstein bild via Getty Images The affair caused such a scandal that Congress got involved. Criticizing the studio for using the affair to promote the film, Senator Edwin C. Johnson called Ingrid "one of the most powerful women on earth - I regret to say a powerful influence for evil." He also pushed for a licensing requirement for actors and filmmakers, with the caveat that licenses could be revoked for perceived "immoral" behavior. Of course, his proposal never made it out of the gate. Bettmann / Bettmann Archive / Via Getty Ingrid had already moved out of the US, but the backlash she faced spurred her to stay away for nine years. Ingrid and Roberto were married from 1950 to 1957. In 1972, Senator Charles H. Percy entered an apology to her into the Congressional Record, calling her "one of the world's loveliest, most gracious, and most talented women [who was] the victim of bitter attack in this chamber 22 years ago." She'd "never forgotten" Senator Johnson's tirade, and the apology came as a "complete surprise." Bettmann / Bettmann Archive / Via Getty 3. Ingrid and Roberto's affair contributed to another shocking moment in Old Hollywood history. The scandal tanked Ingrid's 1948 movie Joan of Arc, driving the final nail into producer Walter Wanger's financial coffin. Over the next few years, he declared bankruptcy, leaving his wife, actor Joan Bennett, as the main breadwinner. However, in 1951, he became suspicious that she was cheating on him with her agent, Jennings Lang. Keystone / Getty Images Like many a scorned spouse, Walter hired a private investigator to tail Joan and Jennings. When the PI discovered the alleged couple was spending time together in Beverly Hills, New Orleans, and the Caribbean, Walter decided to take matters into his own hands. He found Joan's green Cadillac parked outside Jennings's agency then drove around, waiting and armed. In Walter Wanger: Hollywood Independent, author Matthew Bernstein wrote, "There was a violent argument between the two men, with Bennett yelling, 'Get awa
