Aniston, 49, looked glam in a black outfit as she accompanied Cox, 52, to the Chanel Dinner Celebrating Our Majestic Oceans, A Benefit For NRDC.
Aniston wore her hair tousled and sported a long black dress with heels and fitted blazer as she was all smiles at the event.
There have been rumors recently that she will be Cox ‘Maid Of Honor’ at her pending wedding to Irish rocker Johnny McDaid.
Aniston was left devastated when her marriage to Justin Theroux collapsed but she has bounced back and is getting ready for summer.
Her friendship with Cox has never been stronger. A source revealed: “Courteney wouldn’t want to walk down the aisle without Jennifer by her side. They have a very strong friendship.'
Courteney was maid of honor herself when Jennifer tied the knot with her ex Justin Theroux back in 2015 and she comforted her when the union ended.
RadarOnline.com reported recently how the former Friends star Aniston has a crush on Star Wars hunk Oscar Issac.
