We're used to seeing Jennifer Aniston in an array of little black dresses on the red carpet, so we were pleasantly surprised when she upped the fashion ante in a gorgeous Burberry gown for the New York premiere of We're the Millers.

Turning up at the premiere with fiance Justin Theroux, Jen looked stunning in the aubergine strapless dress, showing off her fabulous figure, complete with a sun kissed Californian tan. Proving that less is more when it comes to a show-stopping look, the former Friends star accessorised with nothing but a pair of Casadei heels, simple drop earrings and, of course, her dazzling engagement ring.

Other celebrities in attendance included her movie co-star Jason Sudeikis and his fiancee Olivia Wilde, who wore a pillbox red Osman gown with Jennifer Meyer jewels - tweeting before the premiere, "Wearing red lipstick like I think I'm a grownup. 50 bucks says it's on my forehead by the end of the movie."

Fellow We're the Millers co-star Emma Roberts also stepped out to celebrate the movie, working grown-up glamour in a black drop hem dress from Michael Kors, Casadei shoes and Chopard jewels plus a fabulous Sorellina ring.
