Charlize Theron reportedly wants Tia Mowry off 90s Nickleodeon show Sister, Sister banned from an exercise class.

The Oscar winning actress (that being Charlize) was furious the Instant Mom star branded her "mean" in a recent interview, so asked SoulCycle bosses (that's a spin class, not "cycling with black people") to stop her using the facility as she was concerned about her privacy.

A source told Dish Nation (AKA a rather arbitrary group of people in the below video): "Charlize came in so p***ed off after Tia went to the tabloids about her, and she demanded we bar Tia from ever coming back. When the manager refused, Charlize just got angrier and said she'd go to the top to make it happen."

Apparently Charlize said: "This nobody who was famous for a minute 20 years ago can complain to the tabloids about me but I can't expect you to protect me from hangers-on in your studio?"

Charlize's complaint comes after 36-year-old Tia claimed Charlize rolled her eyes and said "Oh my God" when she attempted to introduce herself to the 39-year-old actress at one of the classes.

Tia added: "I wasn't over-the-top. I know how to approach another celebrity. Charlize was just mean. I'm just being honest."

The good people of Dish Nation are blaming Sean Penn and Charlize's "new haircut" for the alleged influx of mean.
