She isn't exactly known for her racy dress sense or raunchy attitude, but all that may be about to change.
Emily Blunt attended the Los Angeles premiere of Arthur Newman showing her daring side in a keyhole dress on Tuesday evening.
The 30-year-old looked sensational as she walked the red carpet at The Arclight in Hollywood, California.
Emily managed to avoid a wardrobe malfunction as her frock was held together delicately by a few strings.
Although part of her chest was on show she was able to not show any of her cleavage as her black dress revealed just enough skin.
The long black dress fell just above her ankles and showed off her slender arms and part of her neckline.
She accessorised beautifully with a thin black belt that was adorned with black crystals and diamontes as she carried a small clutch bag.
With her hair pulled back and worn up away from her face, the actress looked classy with a pair of diamond drop earrings.
She was joined at the premiere by her co-star Colin Firth, 50, who was as slick as ever in a black suit.
The movie stars Firth as Wallace Avery, a man who hates his life and his job and so fakes his own death in order to start a new life under a new identity.
Embarking on a life changing road trip, Wallace, now named Arthur Newman, meets a troubled woman called Mike, played by Blunt, who is also running from her past.
Drawn toward each other the pair break into empty homes and assume the identities of the absent owners.
