According to People magazine, Hilton went to a club in Las Vegas and revealed Christina Aguilera’s secret.
She announced at LAX Club, "Congratulations to the most beautiful pregnant woman in the world. You’re gorgeous."
The singer who had not yet publicly declared her pregnancy, seemed very surprise by Hilton’s statement. Aguilera hid her face in her husband, Jordan Bratman’s shoulder. She did not seem vexed by Hilton’s outspoken manner, and was even seen laughing with Hilton later that evening.
