17 of 105: Jonah Hill and girlfriend Jordan Klein have broken up after dating on and off for the past four years, Us Weekly reported on Oct. 18, 2011. The two have not commented.

Hill and Klein grew up together in Los Angeles and had largely kept their relationship private. Hill had talked about her during an interview with Howard Stern on the shock jock's Sirius XM radio show in late September 2011 to promote his film 'Moneyball,' which also stars Brad Pitt. At the time, he referred to Klein as his 'girlfriend.' When asked if he planned to marry her, Hill told Stern: 'I don't know, man. She's a good lady.'

Hill, who had months earlier made headlines due to his drastic 40-pound weight loss, rose to fame with his role in the 2007 comedy movie 'Superbad.' He told Stern that after the movie was released, he 'definitely started getting a lot more sexual attention.' Hill said his father told him to enjoy his newfound fame and not 'settle down' immediately.

'I've had a girlfriend on and off for like four years,' Hill told Stern. 'When 'Superbad' came out, we were off. I cleared all this with her.'
