Reese Witherspoon's latest romantic comedy doesn't hit theaters in the US for another two weeks, but the spy-against-spy love story, This Means War, had it's UK premiere Jan. 30.
The actress chose a sparkly black and green sequin Louis Vuitton dress with ruffles and black Christian Louboutin heels to walk the British red carpet.
To complete the look, Witherspoon, who was joined by the film's director McG and her co-stars Chris Pine and Tom Hardy, left her blonde hair long and straight and showed off the return of blunt bangs.
Hardy was sporting a winter beard and wore a bright red scarf over his suit (which was paired with a blue tie), while Pine went classic in a pinstripe suit by Ralph Lauren.
McG went sporty with a blue and white checkered shirt under his grey suit.
