Justin Theroux and Jennifer Aniston left their new Hollywood Hills home for an afternoon lunch date at Chateau Marmont with friend and hotelier Andre Balazs.

Mr. Balazs is currently dating Jen's BFF Chelsea Handler. Talk about the perfect scenario!

Mr. Theroux rocked his usual look ... black jeans, tight t-shirt and aviators. We have to admit, the guy cleans up pretty nicely.

Theroux, 39, and Aniston, 42, recently purchased a $3 million pad in Hollywood ... quite the downsize from her previous $38 million Beverly Hills estate.
