On the red carpet: Courteney Cox, Cameron Diaz, Keira Knightley, Michael Fassbender

Courteney Cox went behind the camera for her first directorial effort Just Before I Go, which premiered at the Tribeca Film Festival.

She turned out in a figure-hugging leather top and sheer skirt, with ultra-dark eye make up. A bit too goth for our tastes.

Cameron Diaz was demure on the red carpet at the New York Cinema Society premiere of The Other Woman in a slinky navy number from Vionnet. The mid length, asymmetrical dress, styled with red lips and nude courts, left one shoulder on show.
