John Mayer celebrated his birthday with ex-girlfriend Jennifer Aniston, fuelling rumours they have reconciled.
The pair - who looked intimate and affectionate - were seen together on Wednesday night at the Grand Havana Room members club in Los Angeles enjoying dinner on a private terrace.
A source said: "They seemed to be having a great time. They were sitting next to each other. They're a very good-looking couple and seemed happy together."
Jennifer and John, who split in August after a three-month romance, sparked speculation they had reunited late last week after they were seen passionately kissing at a Ray LaMontagne concert together before sharing a private plane to Los Angeles.
They were then seen enjoying drinks with friends earlier this week, where a fellow reveller said: "They were holding hands at one point and seemed very much back on."
Early on Wednesday, John, 31, was seen "sneaking out" of the 39-year-old former 'Friends' star's home.
A source claims the two reconciled because Jennifer "can't deny their major chemistry, similarities and ability to laugh at things".
