AP Photo/Lisa RoseJennifer Aniston and John Mayer helped Courteney Cox and David Arquette celebrate their anniversary Thursday night, but that's not what makes them humanitarians.
The foursome got together for Omnipeace.com's dinner party at STK restaurant.
According to People, the two Friends were first joined by John, and then David came along after watching the Lakers-Celtics game at the bar. Ouch!
Once Mayer settled in next to her, Jen was seen slipping her arm around her man. But that wasn't the only PDA between them...
Later in the evening, the group sipped wine while Jen and John held hands under the table.
Could they be following in their married friends' footsteps? After all, Courteney and David were celebrating nine years of marriage that night—despite his apparent fondness for watching sports on TV rather than keeping his wife company.
