HOW AWESOME!  TMZ is reporting that the super fab Gwen Stefani is joining The Voice as a judge for Season 7, which starts taping in June!

Supposedly producers started looking for new blood in February after Christina announced she was pregnant. TMZ was told NBC wanted Christina to stay during her pregnancy but she's having a difficult time already and ultimately bowed out.

Gwen's deal is for one season right now, and we're told Christina has already signed on to rotate back into her spinning chair for Season 8.

I think this is so kickass. Gwen has been in the industry for a LONG time and is very well respected!
