The Hollywood new mummy brigade was out in force yesterday as Jennifer Lopez, Nicole Kidman and Halle Berry hit the red carpet for Elle magazine's Women in Hollywood Event.

But it seems the stress of motherhood has already given Nicole a few extra grey hairs.

The actress - who was guest of honour at the glitzy event - was sporting some silver roots on her normally well-groomed strawberry blonde hair.

As for Jen, her choice of outfit definately divided opinion but it was her makeup that proved the real talking point.

The Latina diva was far from her normal immaculate self, with a shiny complexion and haphazardly-applied eyeliner.

And new mum Halle sparked rumours that she is pregnant again, thanks to a tight-fitted top that showed her rounded tum.
