NBC singing show "The Voice" is rumored to bring back former coaches Pharell Williams and Christina Aguilera in Season 13.

As per INQUISITR, Miley Cyrus posted on Twitter via @TeamCyrusHD account saying there are chances of Season 13 witnessing a different line up of judges alongside Miley.

"Rumor is that along with Miley, the other Season 13 coaches will be Adam, Christina Aguilera, and Pharrell Williams!" the Cyrus update account stated on Twitter.

Miley Cyrus will not come back for Season 12 but will join in Season 13. Gwen Stefani will be replacing Miley for the upcoming season.

On set, tension between Miley, Adam and Blake has been going on for some time, and news of Adam Levine, Blake Shelton, and Gwen Stefani leaving "The Voice" is flying around as well.

Despite rumors suggesting that Adam will appear in Season 13, according to Radar Online, the "Animal" singer has threatened to exit the show if Miley reprises her role. 

The report claimed that Adam thought Miley is the most obnoxious person ever and her thoughts about Adam are somewhat the same.

"Adam does not really want to return if they bring Miley back. He is that over it."

Both Adam and Blake are veterans in the show and have worked with "The Voice" since the beginning. Along with Adam, even Blake has considered that it's the right time to exit the show along with Gwen.

Another source reports to RadarOnline that after the announcement of Gwen replacing the "Wrecking Ball" singer in the next season, Adam was thrilled. He is very happy that Gwen will be back and Miley is gone.

The insider further confirmed that Gwen's boyfriend and co-judge Blake Shelton has not been his old self since his girlfriend departed the show.
