Goodbye, Gwen: Christina Aguilera Returning to 'The Voice'
Since she last sat in the giant red swivel chair, Aguilera got engaged to Matt Rutler earlier this year and gave birth to their daughter, Summer Rain Rutler, in Aug. 2014.
When Aguilera returns to The Voice, she'll rejoin longtime coaches Blake Shelton and Adam Levine -- but this will be the first season she's competing against Pharrell.
Pharrell, incidentally, is currently finishing up work on Stefani's upcoming third solo album. The Voice: It's just one big happy family, right?
