What with Halle Berry, Nicole Richie and Christina Aguilera, it seems you can't turn a corner in Hollywood at the moment without bumping into a pregnant starlet. And what's more, none of them are letting their new larger status ruin their social life. Christina proved this as she walked the red carpet at LAX nightclub over the weekend in Las Vegas. She looked as cute as a doll in a floaty pink dress, but revved it up with some foxy make-up, reminding us all that mum's to be can still ooze sex appeal.
