Jonah Hill, Jordan Klein reportedly split

Jonah Hill shed 40 pounds and now he has shed his longtime girlfriend, Jordan Klein (pictured together above circa May 2010). But according to US Weekly, it's an amicable breakup that has more to do with her new job.

A source tells US, "Jordan always seemed really happy and in love. I never heard a single complaint about their relationship. [The break-up] 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 pair met in high school and were seen together in public as recently as July 2011. Another source tells US the 27-year-old Hill was hanging out at an event with a different girl just a few weeks ago.
