Jennifer Aniston and Justin Theroux head out

The pair sported complementary trilbies as they left the 42-year-old actress' New York flat.

Under their headgear they both wore sunglasses as well, and were united in grim expressions.

The former Friends star and the actor/screenwriter have been dating since June.

And in a gushing magazine interview Jen indicated her actor/screenwriter lover ticks all the right boxes.

Asked what she looks for in a relationship, she said: "I would say I couldn't be in a relationship without equality, generosity, integrity, spirit, kindness and humour.

"And awesomeness."

The pair's latest outing comes shortly after reports Jen's ex-hubby Brad Pitt has offered to donate 630,000 to the charity of her choice, if she and Justin pose for a photo with him and girlfriend Angelina Jolie.

US sources claim Brad wanted the foursome to be snapped together to "show the world he and Jen are on good terms", following his recent comments about his "boring" marriage to the former Friends star.

In an interview with a magazine the star said: "I spent the '90s trying to hide out, trying to duck the full celebrity cacophony.

"I started to get sick of myself sitting on a couch, holding a joint, hiding out. It started feeling pathetic.

"It became very clear to me that I was intent on trying to find a movie about an interesting life, but I wasn't living an interesting life myself.

"I think that my marriage had something to do with it. Trying to pretend the marriage was something that it wasn't."
