"The Voice" season 11 is being hounded by rumors about an alleged feud between coaches Miley Cyrus and Adam Levine which supposedly has long been brewing. This is also speculated to be the reason why Cyrus would leave the hit reality singing competition next season, which in turn became an opportunity for Gwen Stefani to reappear on the show.

According to recent reports, NBC has already confirmed that Cyrus is sitting out "The Voice" season 12 but will return to take her coach position in season 13. Talks have it that the on-going tension between Cyrus and Levine has caused the former to take a break from the show, and both have been constantly arguing since the filming of the current season began. Levine is also said to actually despise Cyrus' loud attitude. These talks, however, were denied by both singers as an unnamed source said that the bickering between Cyrus and Levine was just for mere fun and has nothing to do with personal issues.

Following Cyrus' backing out, Stefani was recently confirmed to return to take the chair of Cyrus in the show's renewal for season 12. Alongside her are confirmed returning coaches from season 11: Levine, Alicia Keys, and Blake Shelton.

"We can't wait to experience the unique chemistry and energy Gwen, Alicia, Blake and Adam will bring to season 12," NBC president Paul Telegdy said. "With Miley returning for season 13, we're truly ecstatic about the unmatched musical know-how and talent coming together in our coming seasons," he added.

Meanwhile, the competition's Knockouts round is currently underway. In line with this, first-time coach Cyrus revealed that she would burst into tears every time she has to eliminate someone from her team. Previous reports say Cyrus has developed a special friendship with her team members and exerts efforts to wear colorful outfits since she believes that her "happy" getups help make her contestants feel safe and calm during the competition.

"The Voice" season 11 currently airs on NBC Mondays and Tuesdays.
