The Claws Are Out! Mila Kunis' Nasty 'Bad Moms' Feud With Leslie Mann Explodes

Mila Kunis is locked in a nasty feud with Leslie Mann, who’s bitter for being left out of her smash hit Bad Moms, RadarOnline.com has learned exclusively!

“Mila is really tired of the backstage drama surrounding 'Bad Moms' and Leslie and her husband Judd Apatow," reveals a source.

As fans know, Mann was originally slated for the lead role but the husband and wife team abruptly dropped out claiming they were too busy to commit to comedy about exhausted mothers battling over-protective parents at their children’s school.

But now, with the explosive success of the franchise, Mann wants back in!

"Now that it's all panned out into a real hit series of films, Mila wants to put the knives away and have a relationship with Leslie and Judd again."

But sources tell RadarOnline.com exclusively "Leslie’s very sore and b***hy about the whole thing and can’t let it go!"

The other problem looming is Judd "is like a dog who's been kicked too many times," spills the informant, adding the producer "just holds grudges forever and rubs his success in people's faces. And this was a case where he made the wrong bet."
