Jonah Hill, whose dramatic weight loss has caused quite a stir, has broken up with his longtime girlfriend Jordan Klein, Us Weekly reported.

Jordan always seemed really happy and in love, a source told Us Weekly. I never heard a single complaint about their relationship. It was probably traveling. She would always go where he was. Now that she has a stable job, she can't just pick up and leave.

The Superbad actor made headlines after dropping a ton of weight over the past year. He was recently photographed while doing promotion for the film Moneyball, costarring Brad Pitt, looking quite different.

Here are photos of the actor today and what he looked like before he lost all that weight.
