Jackson Family Feud Heats Up: Janet Allegedly Slaps Niece, Calls Her A 'Spoiled Little Bitch' (PHOTO)

Somehow we don't think this is what Michael Jackson meant when he wrote the song, "Heal the World."

According to TMZ, an all-out war broke out at the Calabasas, California home of "missing" Jackson family matriarch Katherine Jackson on Monday afternoon, complete with slapping and punching.

Sources tell the site that two SUVs with Randy, Jermaine and Janet Jackson inside, followed a car driving Michael Jackson's three kids (Paris, Prince and Blanket) inside the gates of Katherine's home. TMZ reports that MJ's three siblings, who did not have authority to enter the premises, tried to "strong-arm" all three of Michael's kids, in order to get them in an SUV and take them to Arizona, where Katherine Jackson has been staying.

That's when all hell broke loose!

Sources say a scuffle ensued after Janet tried to grab a resistant Paris' cellphone, and Janet slapped her teenage niece and called her a “spoiled bitch” during a violent face-off outside the home!

Not to be outdone by her aunt's display of violence, the NY Post reports that Paris fired back with her own slap and told Janet, "This is our house. Not the Jackson family house. Get the f**k out!"

Making matters worse, Janet and Paris reportedly weren't the only ones who got physically violent with each other. The NY Post also reports that Trent Jackson (Tito Jackson's son), who is apparently trying to get temporary guardianship of Michael's kids, put Randy in a headlock and punched Jermaine in the mouth.

MTV reported that police were called to the scene but did not make any arrests.

Meanwhile, Katherine Jackson, who was presumed to be missing earlier in the week, is staying with her daughter Rebbie in Arizona while doctors have ordered her to stay away from computers and phones in order to de-stress, according to the AP and a statement released by Jermaine Jackson on Sunday.

Talking about the scuffle with MJ's kids, Randy Jackson admitted to ABC's "Good Morning America," that things "did get out of hand" when Janet, Jermaine and he visited Katherine's Calabasas home to speak with Michael's three kids on Monday afternoon, but he blamed the altercation on security personnel who tried to block their entrance. Randy also denied the allegations that Janet slapped her niece. "There was no slapping or calling of names. That never happened," he told GMA.

"(We were) coming to tell the children that they could talk to and visit with their grandma anytime they want, that she was resting on doctors orders," he added. "We were denied access to our own home."

TMZ has also learned that Tito's son, Trent Jackson, has entered the probate court in downtown L.A., along with an army of lawyers, trying to get temporary guardianship of Michael Jackson's three kids.

Katherine's lawyer, Perry Sanders, tells TMZ, "This is a very tense time when of course we don't feel Mrs. Jackson should be removed as guardian and we would vigorously oppose that on anything other than an extremely short-term basis, until she returns home."

UPDATE: TMZ has now learned that Judge Mitch Beckloff just made Trent Jackson the temporary guardian of MJ's kids and suspended Katherine's guardianship.

Trent's lawyer is expected to file for permanent guardianship of the kids in the next 48 hours, according to TMZ.
