Ashley Greene and Chris Evans: dating?

“Ashley was all over [Chris], and he certainly didn’t mind,” an onlooker told E! News.

“They were dancing together very closely,” continues the source. “It looked like they had a lot of sexual chemistry.”

Since her split from Joe Jonas, Ashley Greene has also been seen in the company of Kings of Leon’s Jared Followill.

A close friend of Ashley Greene insists that the 24-year-old star is just having fun: “Ashley is newly single. She’s hot. Of course she is going to have fun.”
