Singer detracts from her own air time

They both got the good looks, but it appears that only one got the brains. Beyoncé’s baby sis, Solange Knowles, showed a flash of diva-tude during her appearance on a Las Vegas morning news show Wednesday by dressing down a reporter on live TV. The budding solo artist bristled at station KVVU’s request to mention Jay-Z’s Vegas nightclub during the interview. Trouble was, the staff had only asked about raising the subject – during a break – and they agreed not to when Solange’s handler said no. But the singer waited until cameras rolled again to declare: “I have to say that was not a very professional introduction before. Please don’t tie me in with my family and to my brother-in-law’s establishment.” A voice in the studio was then heard saying, “That wasn’t live, Solange. That wasn’t on TV.” The anchor politely apologized anyway, while Beyoncé’s baby sis was left looking all diva-fied for no reason. And for anybody who’s still not clear that the Jay-Beyoncé marriage reports are legit, having Solange refer to the star as her “brother-in-law” pretty much wraps it.

What’s the deal with screw-ups and trouble in Vegas this week? Mos Def completes the performers’ potpourri of embarrassing and allegedly illegal acts taking place in Sin City during recent days: The rap and movie star is being investigated for larceny from a person after he allegedly snatched a camera from a photographer’s neck during a fashion convention at the Las Vegas Hilton. He allegedly created a small cut on the shooter’s hand before handing off the camera to a bodyguard and leaving the scene. Mos has had at least one other encounter with a photographer when he tussled with TMZ.com personnel, unsuccessfully attempting to delete a digital shot that he didn’t approve. Wasn’t there a time when celebs were glad to have their pictures taken?
