John Mayer turns 31 today and last night, he celebrated at the Beverly Hills cigar bar Grand Havana Room with back-on girlfriend Jennifer Aniston by his side.
According to Us Weekly, Mayer affectionately stroked Aniston’s hair while talking on a private outdoor patio.
Jen, 39, and John, 31, started dating in April, but split in August. A source says the two reunited because Aniston “can’t deny their major chemistry, similarities and ability to laugh at things.”
HAPPY BIRTHDAY, JOHN MAYER!
