John Mayer is still pining over the demise of his on-again/off-again relationship with Jennifer Aniston — at least that’s the word from the perky brunette most recently romantically linked to the “Clarity” crooner.

In a new interview with Britain’s Heat Magazine, aspiring actress Scheana Marie Jancan claims that John was “completely shocked” by Jen’s decision to end their romance in March — adding that he spent the better part of her brief time dating him thinking of the former Friends star.

“John was devastated at the break up with Jen. He told me that he really didn’t think Jen would dump him,” she explained. “He’s never really got over it and he still talks about her a lot. He’s been playing guitar alone at night, pining over her.”
