The diva strikes back.

Never one to shy away from dramatics, former Supremes headliner Diana Ross caused a scene in a Beverly Hills restaurant last Thursday after she was told she would have to wait to be seated.

Ross arrived at upscale Italian eatery La Scala to have lunch with her daughter when she was told the restaurant does not seat anyone without a reservation until the entire party has arrived. Because Ross showed up ahead of her daughter, she was asked to wait. She declined and marched on to a corner booth anyway, according to the New York Post.

The Post reports that management walked over to discuss the restaurant’s seating policies with the singer, telling Ross that she would not be served if she didn’t wait for her daughter to arrive. Naturally, Ross refused to move and a scene ensued once her daughter did show up, with both women eventually storming out of the restaurant.

“I’m sorry that Ms. Ross had a problem with that and she feels that the rules didn’t apply to her,” La Scala owner Gigi Leon told the Post. “Our policy is that we don’t sit incomplete parties. If people jump the line, our policy is we don’t serve them, and she was told that. We treat everyone the same, whether you’re famous or not. We love having her as a customer. We’d be happy to have her back.”
