OK! Exclusive: Diva Standoff! Christina Aguilera And Gwen Stefani’s Voice Feud Heats Up And Gets Nasty!

As Gwen Stefani bows out of the judging The Voice, she has no intention of smoothing things out with former swivel chair judge Christina Aguilera. The two music superstars are still in an intense turf battle, with neither wanting to back down first!

Even though Christina left the show seasons ago, she still thinks she owns it! An insider told OK! exclusively that, “Everyone knows Christina think this is her show and she can swan in and out whenever she likes.”

Xtina cannot wait to take back control and make everyone forget about Gwen. She refers to Gwen as “the substitute!”

Gwen isn’t in the dark though! “She knows Christina turns her nose up at her and she’s been told about the ‘substitute’ jibe – and she has a few tricks up her sleeve herself. She plans on going out as THE only coach everyone wants back – the most memorable coach and ‘face’ of the show,” revealed the insider.

The “Bananas” singer is keeping her schedule open just in case Blake Shelton or something else needs to take a season off! “She would love nothing better than to take on Christina face-to-face on that show – and so would a lot of viewers too,” said the source.
