John Mayer to perform for Aniston

Jennifer Aniston has reportedly invited John Mayer to perform at the wrap party for her latest film.

According to In Touch, the cast and crew of Marley & Me, in which Aniston co-stars with Owen Wilson, will celebrate the end of filming today with rocker Mayer giving a special performance.

The original wrap party was scheduled to take place on May 9 but was moved so Mayer could perform a three-song set.

A source said: "Everything was changed last minute so John could do this for her. He's crazy about Jen."

Mayer played down his romance with Aniston after the pair were photographed holidaying together in Miami.
