What’s black, white, and red all over? Miss Christina Aguilera, who’s quickly becoming the celebrity world’s leading hot mama to be (sorry, Nicole Richie). I love how Xtina’s ruby-red Balenciaga purse adds fierceness to her funky black and white ensemble. Now baggy sweats and frumpy mumus for this lady. If only Balenciaga made diaper bags, she’d be all set.
