Leading ladies Cameron Diaz and Jessica Biel proved it's not just their taste in men that they share as they both hit the red carpet in matching dresses.

Cameron took the opportunity to show of her killer pins (suprise suprise, sorry Cam we're just jealous!) in a thigh high monochrome dress.

The Knight and Day actress completed the look with a pair of black satin heels and barely rare make-up.

Jessica Biel decided to give Cam a run for her money in when she too sported the black and white trend. The actress chose a more demure look wearing a drapped monochrome frock. She finished the outfit with a waist cinching belt and glossy tousled hair.

We love Jessica's effort but we think we're going to have to crown Cam queen of the monochrome.

But as ever it's down to you who do you think wore it better?
