BEYONCE'S MOM TINA KNOWLES IS A ROYAL SNOB!

Beyoncé is a diva onstage, but it sounds like her mother is one all the time.

An onset source for Beyoncé's "Best Thing I Never Had" video, which was shot in Westchester County on Wednesday and in Fort Greene, Brooklyn, on Thursday, tells us although the bootylicious Beyoncé was sweet as sugar on set, it was her mother, Tina Knowles, who demonstrated some serious divalicious 'tude.

According to the insider, the four assistants (count 'em!) the elder Knowles had following her around were calling her "Miss Tina" — "which sounded like a joke." But it wasn't: "The crew was told to call her 'Miss Tina' if they were to talk to her at all," our source reveals.

Her real inner prima donna was displayed on Thursday, while the "prom scene" shoot was filmed at the Brooklyn Masonic Temple near the Pratt Institute. Tina, who heads the House of Deréon fashion label with her eldest daughter, "flipped out on the camera guys for making Beyoncé stand near the [video] extras for too long" because there was too much conversation going on between takes. Apparently, Mama T was "worried" the lowly extras would talk to her darling daughter.

But it was the other way around. Beyoncé "was fine with [talking to anyone]. She was making everyone laugh."

Clad in a purple dress, the 29-year-old singer was talking to the cast and crew about how not being prom queen in the video reminded her of how she never wore the coveted tiara at her own high school dance.

But not everything in this video mirrored reality: Our onset source tells us Beyoncé said it was "weird" not to have her real father, Matthew Knowles, walk her down the aisle in the wedding scene, which took place in a Sleepy Hollow country club on Wednesday. (Beyoncé was escorted down the aisle by her father when she wed Jay-Z in April 2008 in the rapper's Tribeca apartment.)

As we reported late last week, Beyoncé flew in from Nice, France, where she was rehearsing a show to film the Diane Martel-directed video. It's no surprise then that rumors flew among cast and crew that Beyoncé's hubby was in his wife's trailer last Thursday in Brooklyn, but sources didn't actually spy the mogul on the set.

A spokeswoman for Beyoncé with reference to Tina Knowles did not get back to us by press time.
