Paris Hilton has a big mouth.
The heiress took the mic at club LAX in Las Vegas this weekend and congratulated Christina Aguilera on her still-unannounced pregnancy!
As Christina sat stunned next to her hubby Jordan Bratman, Paris said, "Congratulations to the most beautiful pregnant woman in the world, Christina Aguilera...You're gorgeous."
Despite a visible bump, Christina still hasn't confirmed her pregnancy.
Later in the night, Paris goes on to dance to her own song, "Stars Are Blind," and "Extra" spotted her getting close with Adrien Grenier!
Does this mean they really are a couple?
