Jessica Alba debuted a new shorter hairstyle at the 'A.C.O.D.' premiere in Los Angeles on Thursday (26.09.13).

The 32-year-old actress joined co-stars including Adam Scott, Amy Poehler and Jane Lynch at the Landmark Theatre in Westwood where she showed off her new look and was dressed to impress in a cropped black top and black skirt.

On her way to the premiere, which was presented by CIROC Vodka, Jessica posted a picture of her newly shorn tresses on Facebook and wrote, 'Love my new haircut @andels thank u! headed to @ACODmovie premiere#thelandmarktheater #LA #ACOD (sic).''

She also tweeted a picture of co-stars Amy and Adam and wrote: ''Can't wait 2 c these cuties @ACODmovie premiere 2nite #theLandmarktheater (sic).''

'A.C.O.D.' [Adult Children of Divorce] tells the story of Adam's character Carter, who is still dealing with his parents' divorce 20 years later and discovers he was an unknowing participant in a study about children of divorce.

He meets Jessica's character when he is lured into a follow-up study and the clean-cut actress plays against type as a tattooed former wild child.

Following the premiere, the entire cast decamped to the W hotel Westwood for the afterparty.

'A.C.O.D.' will be released in the US on October 4th.
