Paris Hilton got on the microphone at a packed Las Vegas nightclub and lavished Christina Aguilera with praise – and in the process revealed a celebrity secret.
"Congratulations to the most beautiful pregnant woman in the world. You're gorgeous," Hilton announced at about 2 a.m. Sunday at an Aguilera-hosted party at LAX Nightclub in the Luxor.
Aguilera, who has never confirmed being pregnant despite a visible bump beneath her pink chiffon mini-dress, 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. (Aguilera's rep declined to comment).
Hilton's surprise announcement, coming after she earlier put her hand on Aguilera's stomach and the pair giggled, was the highlight of the LAX party, one of many rocking Las Vegas on the weekend of the MTV Video Music Awards.
