Queen B's little sis, Solange Knowles, has finally stolen her more-famous sibling's thunder with an elevator performance that could land her a bout with Damon Feldman's "Celebrity Boxing."
The fight took place at an after-party for last week's high-fashion Met Gala in New York City at The Standard, a swanky hotel in Manhattan's Meatpacking District - soon to be renamed Solange's Punchpacking District.
The video, available on TMZ.com, shows Solange, Beyonce, Jay Z and a large bodyguard getting into an elevator. Within a few seconds Solange goes off on Jay, first verbally, then physically, until the bodyguard has to wrestle her away.
But it's an elevator, so away isn't that far.
Beyonce through the whole round? A silent wallflower.
Now comes the hard part: Wading through the next week's rumors to figure out what briefly turned Solange into a crazed sister-in-law.
All we know now is that The Standard Hotel is ticked off: What's the point of being a fancy hotel if A-listers can't go nuts in your elevators without the footage winding up online?
Who's head of security there? V. Stiviano?
Asked about the video yesterday by the Associated Press, the hotel issued a statement, saying it is "shocked and disappointed that there was a clear breach of our security system."
The hotel says the leaked video violates the confidentiality it provides customers.
"We are investigating with the utmost urgency the circumstances surrounding the situation and, as is our customary practice, will discipline and prosecute the individuals involved to our fullest capacity."
Tattle is beginning to wonder if Miley Cyrus is losing her mind.
We get that she's 21, wants to sow her wild oats, be taken seriously as an artist, flaunt her pot-smoking and overly sexualized persona like so many pop stars before her.
But Friday night, according to contactmusic.com, Miley made a surprise performance stop at London's G-A-Y Club, a famed gay and lesbian nightspot, where she took to the stage and rode and licked a giant inflatable phallus.
Then, before performing "Wrecking Ball," she ranted to the audience about how the song was about her ex, Liam Hemsworth (cover the children's eyes and ears):
"Every time you get in your car," Miley said, "you're going to hear my f---ing song on the f---ing radio, you piece of s---. That's right.
"And then I'm gonna take all my clothes off, I'm gonna sit on a big, giant d--- . . . and then I'm gonna hold the record for the most-watched music video on Vevo."
And it gets worse from there. "If I was a dude I'd probably have a really big d---, 'cause I feel really good about myself now."
Tattle's degree is not in psychology, but that doesn't strike us as the diatribe of someone feeling really good about herself. And it's surely not the type of rant that will make Liam regret his decision.
* The sound of music is returning to NBC but this time the sound will come from 76 trombones. The network is planning a live production of "The Music Man."
NBC Entertainment chairman Bob Greenblatt said yesterday the network has acquired rights for a TV version of the 1957 Meredith Willson con-man musical, frequently quoted in our newsroom.
Greenblatt did not say if Craig Zadan and Neil Meron, the producers for "The Sound of Music" and the upcoming "Peter Pan," would produce the live "Music Man." An air date wasn't announced.
* Eminem gave his estranged mom a Mother's Day gift, releasing a Spike Lee-directed music video for an apologetic song that depicts her struggles in raising him.
The Detroit rapper released the video for "Headlights" featuring fun.'s Nate Ruess on Sunday. The song, from Eminem's 2013 album "The Marshall Mathers LP 2," is an extended apology to his mother, Debbie, for the difficulties he caused her.
* Keith Crisco, the North Carolina entrepreneur who was locked in a too-close-to-call Democratic Congressional primary with former "American Idol" runner-up Clay Aiken, died yesterday, still separated by fewer than 400 votes.
Crisco, 71, died from "some type of fall" at his home, according to Robert Lawson, president of Crisco's company, AEC Narrow Fabrics.
"Keith came from humble beginnings. No matter how high he rose - to Harvard, to the White House and to the governor's cabinet - he never forgot where he came from," keeping-it-classy Clay said in a statement. "He was a gentleman, a good and honorable man and an extraordinary public servant. I was honored to know him."
* When Ellen DeGeneres decided to exec-produce the new sitcom "One Big Happy" for NBC, she clearly didn't take the job lightly.
"Ellen did, I'd say, about 10 minutes of warming up the crowd," star Nick Zano said at NBC's upfronts yesterday. "We hear Ellen doing stand-up and the crowd roaring and we're like, 'Damn . . . I hope we're as funny as that.' "
The show is about a straight guy (Zano) who decides to have a baby with his gay BFF (Elisha Cuthbert). Complications ensue when he marries Brit Kelly Brook so she can stay in the country.
Cuthbert hopes she makes Ellen proud.
"I'm playing a lesbian and she is the coolest lesbian on the planet."
Now, now. Let's not judge people by their temperature.
