The actresses' sighting comes amid reports that Cox and Aniston were feuding over who would get married first -- Cox is currently engaged to rocker Johnny McDaid as Aniston is to actor Justin Theroux -- and the fact that Aniston reportedly replaced the Cougar Town actress with Chelsea Handler as her best friend.
"Aniston, 45, is tired of Cox, 49, urging her to get pregnant and would rather hang out with her fun friend Handler, 39," Radar Online reported in May. "And she's even reportedly considering making Handler one of her bridesmaids instead of Cox."
However, Aniston, Cox and Handler were all seen having dinner together Tuesday along with Theroux and McDaid.
After their Friends reunion on Wednesday, the actresses left the restaurant separately. Cox and Kudrow opted for the front door and got right into their cars and Aniston sneaked out the back where a driver was waiting for her.
