Joe Jonas jealous of Ashey Greene’s onscreen kissing!

Joe Jonas is jealous of the kissing scenes his girlfriend Ashley Greene has to share with Jackson Rathbone in the Twilight Saga: Breaking Dawn.

The Jonas Brothers rocker apparently doesn’t like seeing his woman — who plays Alice Cullen — locking lips with her hunky costar.

“Joe isn’t happy with Jackson kissing Ashley,” a source said.

“He knows it’s a film, but these scenes are really hot and heavy. And Joe is more of a singer than an actor, so this is all new to him.

“Joe is very possessive of Ashley, letting everyone know that she belongs to him, especially [when it comes to] Jackson.”

Recent reports claimed Joe has developed strong feelings for Ashley, and though pals insist the feeling is mutual, they still believe Jonas will be hit harder if they eventually go their separate ways,

“They both are still in the trying-to-impress-each-other phase,” a source said.

“If I were to say who wears the pants, Ashley certainly does but Joe doesn’t realize how much power he actually has in the relationship. She likes him just as much as he likes her, but I think he would submit more easily to her and take it harder if they broke up.”
