Are they or aren't they? That's the question after Jonah Hill and his on-again, off again girlfriend Jordan Klein were reportedly caught kissing at a coffee shop on Wednesday. 

"They were walking toward Starbucks," a source tells People. "Then the next thing we knew, he grabbed the back of her head and started passionately kissing her on the side of the street."

The 21 Jump Street star, 29, and his lady love dated for approximately four years before breaking up in October 2011. The two originally met at a private college preparatory high school and then began dating. Sporting jeans and a blue T-shirt, Hill walked into the Starbucks in North Hollywood, CA with Klein and ordered a latte, two iced coffees, bagels and cream cheese.

"As soon as they sat down they started kissing again," the source added. "They were so into each other, it was like there was nobody else in the store. Actually I think they forgot where they were, it went on for at least five minutes."

A former New Yorker, Hill announced his move back to Los Angeles via Twitter last month.
