John Mayer and Rashida Jones Out Together Again!

After the two were spotted at Chateau together this weekend, they attend a charity event together too...get the latest!

Don't tell Jennifer Aniston, but Rashida Jones and John Mayer have been hanging out a lot lately.

After being spotted at the Chateau Marmont Friday night, where he gave an impromptu acoustic peformance, her rep insisted they were having dinner separately with friends.

But just last night, we spotted the two arriving at the Fulfillment Fund Stars Gala at the Beverly Hills Hotel.

Mayer, who was scheduled to perform, hit the benefit nearly 45 minutes late—with Jones just steps behind him.

While he ducked backstage, Jones was quickly escorted into the event...

The singer performed a live set, including a serenade for Judd Apatow and  Leslie Mann, who were being honored.

Rashida also got in on the action, performing a skit at the charity soiree.

If these two keep stepping out together, it's going to be hard to deny the romance rumors for long.
