Gwen Stefani admitted she has a tinge of jealousy about Christina Aguilera returning to the "The Voice" to take the No Doubt star's place. Stefani confessed she feels left behind.  

So, would she come back to the show after her one-season stint as a coach?

"If they asked me, I would... It makes me so jealous when I think they're doing it without me," Gwen told BuzzFeed. "I'm like, 'What is going on? This is so awkward.'"

Christina's return to replace Stefani wasn't a surprise though.

"Everyone knew she was coming back once she left," an insider told HollywoodLife.com. "It was always the plan."

Although Stefani is off the show for now, she did make a connection with fellow coach Pharrell Williams.

"I can't quite put it into words that she does, but we definitely have a connection, a musical connection that continues to evolve," Pharrell said.
