Have I mentioned how much I love a blonde in green? What a glamorous combo. A very pregnant and very blonde Christina Aguilera hit up Kitson for a Rock the Vote party in a green silk ruffle dress by Vanitas. Looks like she's following Nicole Richie, who also wore Vanitas while pregnant. The patent Yves Saint Laurent bag and T-strap Loubs are also divine. Talk about hot mama-to-be!
