NBC’s hit singing reality competition show, The Voice, has lost one of its most powerful voices — fan-favorite judge Gwen Stefani!

RadarOnline.com has exclusively learned from a network insider that veteran Blake Shelton’s lady love will not be returning to the show next season, as she was previously slated to.

“Gwen isn’t coming back to The Voice," the insider said. "Everyone is really upset because she is such a part of their family.”

So is there trouble in paradise for Stefani, 48, and Shelton, 41?

The two lovebirds turned some heads last night when they attended the American Country Music Awards Las Vegas, Nevada, together.

Two days prior, on April 13, the duo turned even more heads when a portion of Las Vegas Boulevard was closed down as the No Doubt singer made her official arrival to Planet Hollywood Resort & Casino, where they will be performing a 25-show residency beginning on June 27.

“I just gotta take a second to actually believe this is happening,” Stefani told the crowd. “Imagine, I’m just a girl from Orange County in Anaheim, California, and never in my wildest dreams could I imagine that I’d be doing my own Vegas residency.”

According to the source, “Gwen was forced to choose between doing her residency and doing The Voice and her choice was obviously a good one.”

“This is a once in a lifetime opportunity and Gwen knows that she is welcome back on The Voice whenever she wants to," the source said. "Blake and Gwen have such good chemistry and Blake is not going anywhere.

The insider added, “She is going to do her Vegas thing and he fully supports this decision.”

RadarOnline.com reached out to NBC, who confirmed that Stefani will not be returning.
