John Mayer and Jennifer Aniston at a humanitatian event at L.A. steakhouse STK. Courteney Cox and David Arquette were at the event with the couple.

Although the two have been photographed getting cozy, Jennifer Aniston and John Mayer went to their first public event together Thursday night.

They joined Courteney Cox and David Arquette — who celebrated their nine-year anniversary that night — at a humanitarian event at L.A. steakhouse STK.

The bash was in honor of Jeffrey Sachs — who is known for his charity work with Angelina Jolieand is pals with Aniston’s ex husband Brad Pitt.

I’m still waiting for the first time that Angelina and Jennifer meet publicly, if that ever happens.
