New celebrity couple Jennifer Aniston and John Mayer took their relationship to the next level: meeting the friends.

Aniston, 39, and Mayer, 30, visited Jennifer's best friend and "Friends" co-star, Courteney Cox and her husband, David Arquette, over the weekend.

Cox, 43, is said to be very protective of Aniston, who she supported following her high-profile marriage split with Brad Pitt in 2005. She was rumoured to have disapproved of Aniston’s last long-term boyfriend Vince Vaughn.

Aniston and Mayer went public in recent weeks while the actress was in Miami shooting "Marley & Me" alongside Owen Wilson.

Mayer said recently of his romance with Aniston that, "This is not a scandal, this is not an issue, this is not a problem, this needs no spin control. This is me living my life."
