Michael Jackson's daughter Paris made a bombshell announcement to friends ... telling them the MJ album released in the wake of the singer's death did NOT contain MJ's actual voice ... it was an imposter.

TMZ has learned ... the announcement was made during an online video chat with several friends in 2010 ... just before the "Michael" album was released, which contains several previously unreleased tracks allegedly performed by Michael Jackson. 

The video chat was recorded ... and Paris joked about the footage eventually "leaking" to the Internet.

Paris had made the announcement in the midst of rumors that MJ's parts on the "Michael" album were REALLY performed by an MJ sound-alike named Jason Malachi ... but both Jason and Sony denied the allegations.

During the video chat, Paris played one of the songs from the album, "Hold My Hand" ... and one of her friends asks why the singer doesn't sound like MJ. 

Paris replied, "It's NOT him ... the whole album isn't even him!! Go online ... go on YouTube and look up Jason Malachi. That's him!!"

She continues, "I should know if it's him or not because he would sing to me all the time."

TMZ has learned a recording of Paris' video message is being shopped to various media outlets ... and we're told "Offers are on the table."

Not even Michael Jackson's 13-year-old daughter Paris can resist the charms of Justin Bieber -- introducing him moments ago at her father's tribute show in Hollywood ... and nearly melting in the process.

In her intro, Paris said, "We are all very big fans of [Justin] and his music" -- and then, with a coy smile, she added, "I know I am."

Justin then emerged and performed his own rendition of "Rockin' Robin" -- which MJ famously covered on his first solo album back in 1972. It wasn't half bad either.

Prince, Paris, and Blanket Jackson just left a lasting impression on Hollywood -- sinking their father's shoes and sequined glove into wet cement in front of the historic Grauman's Chinese theater.

It was all part of a tribute ceremony for the King of Pop this morning -- to immortalize the singer alongside Hollywood legends like Cary Grant, Marilyn Monroe, and Clark Gable.

In addition to the entire Jackson family, a laundry list of celebs were in attendance ... including Justin Bieber, Chris Tucker, and Smokey Robinson.

Paris Jackson really is a chip off the old King of Pop.

In the middle of playing high school softball the 13-year-old outfielder broke out one of her late dad Michael Jackson's famous dance steps.

She's got the moves like Jackson.

Michael Jackson's three kids -- Paris, Prince and Blanket -- along with a few other family members, attended "Michael Jackson: The Immortal World Tour by Cirque du Soleil" in Las Vegas last night.

The show starts its tour in Vegas before making its across the U.S. in 2012

Katherine Jackson says immediately after Michael Jackson was pronounced dead, his daughter Paris was crying, saying, "I wanna go with you." -- this according to the official Probation Report obtained by TMZ.

In the report, Katherine lashes out at Murray for his documentary, in which he lays blame for MJ's death on the singer and not Murray himself.  The report says, "During filming, he repeatedly stated that he did nothing wrong.  Ms. Jackson feels this adds insult to injury, and shows that he is clearly not remorseful."

Katherine feels a 4-year sentence is "insufficient."

Katherine also says she was "deeply insulted" that on the anniversary of Michael's death, Murray arranged to be photographed at the cemetery.

With the fate of Conrad Murray still hanging in the balance, Michael Jackson's children -- Prince, Blanket and Paris (in the white hat) -- went to the movies last night and saw "Tower Heist."

According to our sources, Katherine has been filling the children in on the details of the trial herself -- she'd rather they hear it from her and not through anyone else.

We're told when the verdict comes down, Katherine will be the one to tell them the news.

Jurors did not reach a verdict on Friday and deliberations will continue Monday morning.

Like a 13-year-old Mike Singletary ... Paris Jackson was a focused instrument of destruction as a linebacker during a flag football game in L.A. yesterday.

Jackson -- who's the very first female in the history of her private school to join the squad -- also played a little offensive line ... and got STRAIGHT UP PHYSICAL with the boys, throwing some pretty aggressive blocks.

But Paris wasn't the only celebu-spawn on the gridiron ... Oksana Grigorieva and Timothy Dalton were standing on the sidelines to support their son, Alexander, who's also on PJ's team.

Jackson's school emerged victorious ... and after the game, she tweeted about it ... saying, "We Won 32-6!!!!!!!! Yeahhh Boiiiiii!"

Michael Jackson's daughter is in love with Chris Brown ... and last night at his L.A. concert, the singer made sure the King of Pop's little girl got nothing short of the royal treatment.

Sources close to Brown tell TMZ ... once Chris learned Jackson would be attending the show, he invited Paris to the pre-show soundcheck ... where he greeted her with a giant, friendly hug.


After the warm up, Jackson made her way to her front row seat with some of her friends ... and rocked out to the sold-out show ... along with a ton of other stars including Jamie Foxx, Damon Wayans, Sean Kingston and Kendall Jenner.

It's good to be The King ...'s kid.

Michael Jackson's 13-year-old football playing daughter is being recruited to be the face of an organization that swears it's helping break down barriers for women ... problem is, it's the Lingerie Football League.

TMZ has learned ... the LFL took notice when Paris Jackson became the first female in her L.A. private school to join the flag football team earlier this month ... and fired off a letter to the MJ Estate in the hopes PJ would be the spokesperson for the league's "youth program."

In the letter, obtained by TMZ, LFL Commissioner Mitchell S. Mortaza acknowledges a "lack of options for competitive female football" ... and says the league will "be introducing youth clinics across the country to introduce the game of football to young ladies at an earlier stage in life."

Mortaza adds, "We ... would like to invite Paris to become the spokesperson for the LFL's youth program and perhaps start training for a future football career in the LFL when she reaches the age of 18."

LFL officials tell us no one in the youth program will wear lingerie.

Mitchell makes a good point about the lack of football options for girls, but is a league that parades adult women around in their underwear really the right fit for mentoring KIDS????

We gotta ask ...
