Courteney Cox and David Arquette Double Date With Jennifer Aniston and John Mayer

Courteney Cox and her husband David Arquette chose to celebrate their nine-year wedding anniversary on Thursday (12Jun08) with a low-key double date - with pals Jennifer Aniston and John Mayer.

The two couples enjoyed a meal at Los Angeles' STK restaurant, where Aniston and Cox had been attending a humanitarian event.

Mayer was the first to join the pair, greeting Cox with a kiss on the cheek before seating himself next to girlfriend Aniston.

And Arquette, an avid backetball fan, completed the party when he came over to the table after watching his beloved Los Angeles Lakers lose to the Boston Celtics on a TV at the bar.

Rocker Mayer, 30, appears to have won the approval of Aniston's best pals - the foursome seemed at ease with one another, just two weeks after the Arquettes were first introduced to Aniston's new beau.

Former Friends star Aniston, 39, took Mayer to meet the Arquettes earlier this month (Jun08), when he accompanied her to visit the couple's new home in Malibu, California.
