Miley Cyrus is getting the chair. We've learned she'll be a coach on "The Voice" Season 11.

It's a big deal for lots of reasons. It's an extremely high-profile show, and producers have decided not to rotate Gwen Stefani back into a coaching role, currently held by Christina Aguilera.

Our sources connected with the show say Miley will be a key player because she appeals to the desired TV demo.

It also means Shakira's on the back burner.

Blake Shelton and Gwen Stefani may be the real deal, because not only is sweeps over, the show's done too ... but they're still together.

Blake and Gwen left the after-party for "The Voice" Tuesday at Avalon in Hollywood, and they sure seemed together.

As for how long it will last ... the bets are on.

This thing might be real after all ...

Blake Shelton playfully gnawed at Gwen Stefani while "The Voice" was on a commercial break Monday night.

Officially, for all the doubters, the TV sweeps period ended 12 days ago -- so maybe they're not together just for ratings.

Then again, for you true believers ... there is still a 'Voice' finale to promote.

Blake Shelton does not sound like a man head over heels in love these days.

The country star was heading into a studio Wednesday when the photog asked about his relationship with Gwen.

Listen closely. He qualifies his answer with the always dreaded word "friends."

Blake Shelton gave Adam Levine an opening on "The Voice" Monday night, and Adam seized the moment by poking fun at Blake's relationship with Gwen Stefani.

Here's the context ... Gwen was Craig Wayne Boyd's coach during Season 7, and got him to cut his hair. Gwen ended up letting Craig go, Blake took him and Craig won.

Now watch the clip ... Blake's doing a call back to Season 7, but Adam is lying in wait and not only made it seem like Blake was referring to his relationship with Gwen, he even mocked her laugh.

Adam's funny.

Miranda Lambert claims cheating was not the only reason her marriage fell apart ... Blake Shelton was way more into "The Voice" than her, and she felt like an abandoned wife ... so say our Miranda sources.

Our sources say Blake's hit TV show was a constant source of conflict between them. She says he had to spend between 7 and 8 months a year in Los Angeles ... a place she "hates." Nevertheless, the sources say she would fly to L.A. to see him -- sometimes just for a day.

But Miranda claims he rarely reciprocated by coming to Oklahoma or wherever she was working.

The sources say Miranda felt abandoned and ultimately said, "This is no way to live."

As for the cheating ... both sides are not backing down and accusing the other of infidelity.

Joshua Murley -- a Season 6 contestant on “The Voice” – was arrested at a Texas Walmart after allegedly stealing $57 worth of munchies.

Cops tell us Murley hit the self-checkout, bagged his groceries, then left the store without paying. His booty included chips, dips, drinks and bread.

He was booked on misdemeanor theft -- it is Walmart -- and spent the night in jail.

Murley was part of Team Adam, and later poached by Team Shakira on the sing-off show, but he never made it to the playoffs.

Only chair that’s gonna turn now is the judge's.

A rep for the medical examiner's office tells TMZ ... Riley hung himself.

Anthony Riley -- an insanely talented singer who competed on "The Voice" in 2015 -- was found dead Friday ... and friends say it appears Riley took his own life.

Riley -- a Philadelphia street performer -- was a smash hit from the moment he first appeared on "The Voice" -- with all 4 judges slamming on their buttons within seconds of his performance of James Brown's "I Feel Good."

He later left the show in January to deal with substance abuse issues.

A close friend of Riley's told Philly.com his body was discovered in the basement of the apartment where he had been saying ... and all signs pointed to suicide.

He was 28.

"The Voice" host Carson Daly posted a message about Riley ... saying, "Praying for the family and friends of Anthony Riley today. It's a heartbreaking loss. He was incredibly talented and loved to sing. God Bless him."

Prince shamelessly stole a recording artist away from the producer who discovered Lady Gaga ... and her company is now going after The Purple One in court ... this according to legal docs filed by fame music producer, Jolene Cherry.

Singer Judith Hill made a name for herself on "The Voice" in 2013. Sony got interested in her. Ditto Cherry, who says she also first eyed Lady Gaga. Sony and Cherry partnered and claim they signed her to an exclusive recording deal.

According to the lawsuit ... a few months ago, Cherry heard rumblings that Hill was meeting with Prince for a recording session. Cherry claims she warned Judith to stop earlier this month, only to learn that she and Prince recorded an entire album -- 11 songs -- and released it Monday as a free Internet download.

Cherry is now going after Prince with a vengeance, courtesy of her lawyer Larry Stein, asking not only for regular damages but punitive damages for underhandedness.

Judith's attorney Peter Haviland tells us Cherry's suit is simply a publicity stunt ... since Judith already has a pending lawsuit to confirm she is free from Cherry. He adds, "Prince has done absolutely nothing wrong. Judith was and is absolutely free to perform her music as she has done."

With Season 8 kicking off, allow us to remind you of the past champs -- and show you what they look like now. See how many you remember!

Craig Wayne Boyd says he has a damn good reason for blowing off his fans right after he won "The Voice" ... he didn't want to be late for a meeting with Donald Trump.

You'll remember ... Boyd and his hair were in New York City last month after the big win. On his way out of a building, he kinda let one fan take a pic with him ... but straight up blew off a bunch more.

Boyd was back in NYC Wednesday night and revealed how the Donald, unknowingly, played a part in the snubbing.

So, has Boyd learned his lesson? As luck would have it ... a few fans walked up to him last night. Check out the interaction.

Judith Hill -- who's signed to Sony's music label and was a contestant on "The Voice" -- reportedly recorded a new track giving praise to Kim Jong-un while roasting James Franco ... but her people say the story is bogus.

According to Page Six ... Hill originally wrote an ode to James Franco and reportedly submitted it to "The Interview" producers for the soundtrack. But when it didn't make the cut -- and the hacking scandal went down -- she changed the lyrics and the title to "A Love Letter to Kim Jong-un."

Hill was reportedly attempting to mediate peace between North Korea and the U.S. by making K.J.U. the object of her affection in the song. Some choice lyrics:

- "You got me transcending heaven, so don't be confused ... James Franco ain't got nothing on you."

- "I could wait here 127 hours ... it's true ... there's only Oscar and baby it goes to you."

Hill was reportedly signed to Sony last year ... and is best known for performing with Michael Jackson in the movie "This Is It." She placed in the top 8 on "The Voice."

A rep for Hill tells us they did NOT submit the track to "The Interview" producers ... it was requested of them by a Sony A&R rep. She also says the song is not putting James Franco down.

The rep also claims she was not attempting to mediate peace ... and never changed the lyrics or title. The rep says it was simply a parody version of her song.

Christina Aguilera is not in the Christmas spirit ... she spent her birthday in "The Happiest Place On Earth" ... in a heated argument with Mickey Mouse ... TMZ has learned.

Our theme park source tells us while ringing in her 34th b-day at Disney California Adventure, Christina and her crew tried to get a pic with Mickey, but he was going on a break ... so Christina was told she had to wait. Cue meltdown!

Aguilera lost it, and called Mickey an "a**hole." We're told she even dropped the dreaded, "Do you know who I am?"

Xtina's crew started hurling threats, we're told ... and Mickey had to be ushered to a safe zone -- out of public view. Security was called, but by the time they arrived ... the former Mouseketeer had already split.

Aguilera's rep had no comment.

Craig Wayne Boyd just won "The Voice" and he's already got fans flocking around him in NYC ... which would be awesome -- except for the fact he blew off a bunch of them.

CWB -- not just a great singer, but a great hole digger!

Craig Wayne Boyd may have just won "The Voice," but he wouldn't even be a finalist in "The Brain," because he almost immediately disrespected the fans who will determine his long-term success.

Boyd was leaving an NYC office Building Wednesday ... when he squeezed in an autograph and a mid-stride selfie, and then blazed past the other fans.

The little people know the game, and warned the singer he's starting off on the wrong foot.

"The Voice" is a really good show. Now name one of the past winners.

"The Voice" contestant Delvin Choice is influenced by R&B legend Usher, and cops say he's also influenced by drugs or alcohol ... because Choice got busted for DUI.

Choice -- who made it to the top eight on "The Voice" last season -- was arrested shortly before 2 A.M. Sunday in South Carolina ... after a state trooper pulled him over.

Law enforcement tells TMZ ... it's Choice's first offense. He was taken to jail ... and freed after paying $1229.50 bail.

Choice's father -- who's a Baptist pastor -- told the media, "We all make mistakes in life. We learn from our mistakes."

It's all about choices.
