Jonah Hill has reconciled with his ex-girlfriend.

The This Is The End actor was spotted kissing Jordan Klein - whom he dated for four years before they split in 2011 - in North Hollywood earlier this week. "They were walking toward Starbucks. Then the next thing we knew, he grabbed the back of her head and started passionately kissing her on the side of the street. As soon as they sat down [in Starbucks] they started kissing again. 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 source said.

In September, Jonah and Ali Hoffman called time on their relationship after nine months together. Moneyball star Jonah, 29, is said to have been close to Ali, 24 - the daughter of actor Dustin Hoffman - for some time before they started dating, and even went to the same school, Crossroads High School in Santa Monica, although they were in different years. Dustin also had a hand in Jonah's career, spotting him while he was still in high school and helping him land his first role in I Heart Huckabees.
