Jennifer Aniston and John Mayer reportedly reunited this week to celebrate the singer's 31st birthday together.
The former couple appear to be getting up close and personal again after the exes were reportedly seen cosying up at John's party - prompting speculation that their rendezvous in New York was more than a one-off.
A source tells People.com, "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."
The actress and John were rumoured to have shared an intimate dinner in the Big Apple before sharing a private 'lingering kiss', earlier this week.
