Jonah Hill and girlfriend break up

Funny man actor Jonah Hill and his longtime girlfriend, Jordan Klein, have split.

“Jordan always seemed really happy and in love. I never heard a single complaint about their relationship,” a source told Us Magazine.

"It was probably traveling,” the source continued, reasoning the breakup. “She would always go where he was. Now that she has a stable job, she can't just pick up and leave.”

Hill, best known for his character in Superbad, and Klein were dating on and off for 4 years, On The Red Carpet reported.

Hill has recently shed about 40 pounds for a role in an action-packed flick, 21 Jump Street, so maybe sporting a new look made him decide on the “off” option once again.

The now-exes grew up together in Los Angeles and went to high school together. However, he was reportedly seen with another girl just a few weeks ago at an event.
