Cee-Lo Green and Christina Aguilera of NBC’s “The Voice”

*Christina Aguilera says she was glad to see someone else take over her swivel chair for a minute at “The Voice.”

The singer, along with fellow judge Cee-Lo Green, took the 2012 season off – leaving remaining judges Adam Levine and Blake Shelton to work with stand-ins Shakira and Usher.

“Honestly, for me, I was happy that someone filled the spot for a second, because I had to step away,” Aguilera told us during the TCA Summer Press Tour. “[In] 2010 I joined the show, and it was a time where I needed to sort of dive into something else outside of myself. [But] then it was like this train that kept gaining and gaining and gaining more viewers as each season went on. And I needed a moment to step away. And thank God for Shakira. She did a beautiful job. And Usher apparently came and stepped up with a lot of creative stuff.

Cee-Lo, meanwhile, was a tad less enthusiastic about Ursh taking his place. Listen below.

“The Voice” airs Mondays at 8/7c and  Tuesdays at 9/8c on NBC.
