Only ET has your first look at what to expect from Xtina's big return to the NBC series and a sit-down interview teasing two big new projects off-screen.
"When I'm not doing The Voice, this particular time around, I'm working on multiple albums," she says in the video above. "One being a follow-up to my debut Spanish album, [and] a few solo projects with some incredible producers."
Aguilera says that she's "reuniting" with a few of said producers and they're making "classic magic" in the studio.
"I'm super, super excited," she gushed. "I'm more inspired than I've been in a really long time. It's a really, really exciting time for me."
But when she's not hard at work, Aguilera spends her time at home practicing yoga in her backyard and chasing after her 14-month-old daughter, Summer Rain, who is now walking and talking! "Momma needs to get back to work!" she jokes.
Aguilera returns to a panel that includes Adam Levine, Pharrell Williams and Blake Shelton. The latter's girlfriend, Gwen Stefani, is sitting this round out, but will appear on the show as a mentor to Team Blake. Meanwhile, the 6'5” country star can't help but tease Aguilera in the clip, awkwardly joking about smelling her hair during a promo shoot. (You're gonna want to see the moment for yourself in the video above!)
But the singer gets serious while discussing her recent relief trip to Ecuador.
"I'm half Irish on my mom's side, and half Latin, half Ecuadorian, and I've never been to where my father was born," she says. "I go to feed the hungry as a UN ambassador for world hunger with the World Food Program, and we go into the field where aid is really needed. It's the most amazing, humbling, awesome experience, giving back a little."
Aguilera has been working with the UN and Yum! Brands World Hunger Relief for several years, embarking on trips to Guatemala, Haiti and Rwanda. See what she had to say about why it's a cause so near to her heart in the video below.
