Jennifer Aniston to John Mayer: Meet Courteney Cox!

Jennifer Aniston takes musician boyfriend John Mayer to visit BFF and former Friends costar Courteney Cox at her gated beach home in Malibu, California on Sunday.

Aniston, 39, and Mayer, 30, drove together in his Porsche Cayenne Turbo and spent the afternoon with Cox, 43, and her husband David Arquette, 36. Aniston and Cox definitely like their men younger — fresh meat!

John was also seen walking the stairs up to the main house holding Jen‘s waist.
