Chalize Theron REALLY has it in for this former child star!

Who doesn’t love a good celebrity feud? Even better when one of the celebrities involved is a 90s star trying to claw their way back into the limelight.

Enter: Charlize Theron and Tia Mowry, of Sister, Sister fame.

Tia has been bad mouthing Charlize Theron (is she crazy? Has she not seen Monster?!). The two women go to the same indoor cycling studio at a SoulCycle gym in LA, and according to Tia, when she approached Charlize at the studio, the Oscar winning actress just rolled her eyes and said: “Oh my God”.

Now, we wouldn’t fancy someone doing this to us either, but we wouldn’t go blabbing about it! Charlize is now VERY angry. A SoulCycle insider has claimed:

“Charlize came in so p****d 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 was also heard saying: “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?”

Yikes – this is getting nasty! Looks like Tia better find a new gym!
