Ashley Greene doesn't want to talk about her split with Joe Jonas.

Because she was so hurt by the adorable singer? Perhaps. Or maybe because she's already moved on from him.

Earlier this week, Greene was spotted at Hollywood club Trousdale and, according to an onlooker, "was all over [Chris Evans]." That movie star's reaction, this witness adds: "He certainly didn't mind."

The Twilight Saga actress and the new Captain America - watch the trailer HERE - were spending time at Frankie Delgado's table when they weren't grinding up on one another.

"They were dancing together very closely," says an E! News source. "It looked like they had a lot of sexual chemistry."
