Aguilera seemed to confirm the news herself on Tuesday when she tweeted a welcome to Stefani on Twitter. So excited to have you join #TheVoice squad @GwenStefani! Welcome to our crazy fam! Kisses- xoxo #blondesdoitbest" Christina Aguilera (@xtina) April 29, 2014 Aguilera plans to take a break from "The Voice" in order to give birth and care for her daughter. She and fiance Matthew Rutler got engaged in February, and announced their pregnancy one week later. "She's friends with the other coaches but has a strong opinion, which is also important," host Carson Daly recently said of Stefani. "They can't all just be too lovey out there. So I think she'd be a solid choice."
