It sounds like a certain movie star is jumping back into a relationship with his ex.

21 Jump Street star Jonah Hill split from longtime girlfriend Jordan Klein back in October 2011, but the two were seen kissing on May 22, according to People.

"They were walking toward Starbucks," a witness says. "Then the next thing we knew, he grabbed the back of her head and started passionately kissing her on the side of the street." We're starting to perspire just thinking about this hot moment.

Once the pair entered the Starbucks, they continued going at it.

"As soon as they sat down, they started kissing again," says the source. "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," adds the insider. Nothing wrong with a little PDA with your latte, right?

Jonah and Jordan dated for four years - meaning they were together pre-Superbad - but parted ways in 2011. Their split occurred around the time that Jonah lost a ton of weight for his Oscar-nominated role in Moneyball.

Since then, Jonah — who stars in this summer's comedy This Is the End — has been linked to Dustin Hoffman's daughter Ali.

Looks like this is definitely not the end for Jonah and Jordan.
