Paris Hilton: Christina Aguilera is Pregnant!

Christina Aguilera shows her visible bump beneath her pink chiffon mini-dress as she hosts a party at LAX Nightclub at the Luxor Resort & Casino in Las Vegas on Saturday.

Big mouth Paris Hilton spilled the beans at 2 a.m. today when she got on the microphone telling Christina, “Congratulations to the most beautiful pregnant woman in the world, Christina Aguilera. You’re gorgeous.” Not BFF Nicole Richie?

Here’s People‘s account:

“Aguilera, who has never confirmed being pregnant, appeared temporarily shocked as she sat in her perch in the elevated VIP booth. She sank her head into the shoulder of husband Jordan Bratman as her friends looked stunned.

But she quickly recovered, and the two looked at each other and laughed as the crowd – which included Adrien Grenier, Melanie Brown, Criss Angel and cast members from The Hills – erupted in applause.”

Congrats to the happy couple!
