Highly cosmeticized blonde Americans Christina Aguilera and Paris Hilton were spotted entering London’s Whisky Mist nightclub Wednesday night.

The ready-to-spawn-again Xtina was accompanied by her husband, Jordan Bratman. Paris, per usual, was accompanied by a general sense of entitlement and vacuousness.

Both ladies were sporting some big puffy lips.

Christina is known for her heavy hand with the lip color, but has Paris been fooling about with the collagen?
