The Voice Returns Next Monday

Christina Aguilera may be taking a break from "The Voice," but that's not stopping her giving her former co-judges a piece of her mind.  The singer tweeted Blake Shelton and Maroon 5's Adam Levine on Monday to remind them to give her replacement, Colombian superstar Shakira, a warm welcome when the show premieres next week.  Christina told them to watch their "locker room humor" and treat Shakira "like the lady she is."  Usher will also replace Cee Lo Green this season.

As the show prepares to go up against "American Idol" in another ratings feud, NBC has announced its schedule for the upcoming season.  "The Voice" will start out next Monday with a two-hour premiere special with blind auditions.  Knockout rounds will begin at the end of April, and the top 12 will be unveiled in a special Wednesday episode in May.  A winner will be crowned in June.
