MTV: Christina Aguilera

When I walked up to Christina Aguilera's house, I thought to myself, "Do all of these places just look the same, or was this Ozzy's house?" Sure enough, it was the same house where I interviewed Ozzy Osbourne almost 10 years ago. He showed me the recording studio in his backyard, where the engineer cranked Sabbath's "After Forever."

This time it was Christina sitting in the same studio. She's changed the decor, but she kept the crosses on the doorknobs. She has a sweet GNR pinball machine, too.

HERE is Christina telling me about her "bad girl" image in her new video and in the past. And HERE we are speaking about about how the contestants on "The Voice" helped inspire her new album.
