The newly engaged couple are all smiles as they dine with Cox at the Sunset Tower in L.A.
If you wanna be my lover, you gotta get with my Friends!
“Jennifer looked adorable!” an onlooker tells PEOPLE. “She looked so pulled together and very chic. She was dressed casually, but in heels.”
“They were very calm and carrying on a regular dinner conversation,” the source adds. “Jennifer had a big smile on her face. She and Justin both looked very happy.”
It was the first time Aniston and Theroux have been seen out together since their Aug. 12 engagement.
The Sunset Tower holds fond memories for the couple. It’s where Aniston and Theroux were first spotted out together publicly when they shared a three-hour casual dinner back in May 2011.
After dinner, the trio greeted designer Tom Ford, seated at a nearby table with Tom Hanks and Rita Wilson – who double dated with Aniston and Theroux last April – and several others. Ford was celebrating his 51st birthday.
