Gwen has signed on to be a judge on "The Voice."
Multiple sources connected to the show tell us ... No Doubt's
lead singer will be on Season 7 which starts taping in June.
Producers started looking for new blood in February after
Christina announced she was pregnant. Makes sense ... she'd be 8 or 9 months
along by the time Season 8's battle rounds began.
We're 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.
NBC had no comment.
