In the promo, just before the beginning of a blind-audition performance, Blake Shelton can be seen telling Aguilera, "Going to be good Christina, I can feel it."

Aguilera is back to the show after missing from Season 9. Gwen Stefani, who has served as a regular coach on the previous seasons of "The Voice," won't be coaching this season. However, as reported by US Weekly, she will return as an adviser to Shelton's team, who also happens to be her boyfriend.

Aguilera can be seen asking a female competitor, "Should we just make out now?" and kisses her afterwards. Levine gets up from his chair in excitement and claims, "Greatest moment of the show's history."

Aguilera talked with Parade Magazine regarding how different the show will be this season as compared to the previous ones and also discussed contestants' reaction to criticism.

"I'm trying to make it different by winning this year. And as I said, I've been taking notes. I'm very strategy‑less, though. As a coach, I find that to be one of the biggest things that I try to help them with, is helping them with their head space and their mindset, encouraging them to move forward, and have fun with it. That's ultimately what we're all in the music business for."

This season's coaches are namely Blake Shelton, Adam Levine, Christina Aguilera and Pharrell Williams. Jordan Smith of Levine's team had won the crown in Season 9.
