1970s: Jack Nicholson Cheats On Angelica Huston
Jack Nicholson and Anjelica Huston had a decades long on-and-off relationship that lasted for 17 years. The two met at one of his house parties in the '70s, and he was a womanizer right from the onset of their relationship. On their first date, he cancelled because of a "previous obligation" — which she later found out was his ex-girlfriend, Mamas & the Papas singer Michelle Phillips. 

Then on one of their dates, fed up with watching Nicholson flirt with a German model at their restaurant, she stood up to go. But he grabbed her wrist and pulled her back down to the table, saying, "Don’t ever stand up like that to leave." Huston liked the machismo of it, admitting, "I enjoyed his brief flash of possessiveness.”

While they had their ups and downs throughout their romance, things ended when Nicholson told Huston that he was having a baby with actress Rebecca Broussard.
