Singer Christina Aguilera's pregnancy has been inadvertently confirmed by socialite Paris Hilton, who revealed her friend is expecting a baby to a packed crowd in a Las Vegas nightclub.
The pair was partying at LAX Nightclub in the Luxor hotel on Saturday night when Hilton grabbed a microphone and paid tribute to Aguilera, as she and her husband Jordan Bratman looked on in shock.
Hilton said, "Congratulations to the most beautiful pregnant woman in the world. You're gorgeous."
