Xtina Jr.? OK, we're not sure about the rumors about Nicole Richie being preggers with Joel Madden's baby, but according to Page Six, Christina Aguilera is definitely expecting. "She's been telling friends," one insider says. "She has to be three months [along] now because she's announcing it."

Xtina's getting down to baby business. First on the list, buying a house suitable for a family. In fact, Sharon and Ozzy Osbourne tell UK's The Sun that Christina and hubby, Jordan Bratman, recently purchased their house.

Yay for a mini Mouseketeer!
