Chelsea Handler Says ‘Loser’ Heather McDonald ‘Should Really Be Scared’ After Bad Mouthing Her

The war has been waged! After Heather McDonald bashed her former boss Chelsea Handler, the ex Chelsea Lately host fired back and it wasn’t pretty!

Handler, 40, went on Dirty Sexy Funny to discuss the feud after McDonald, 45, said she “lived in fear” while working on the E! show from 2007 to 2014. “She should really be scared,” Chelsea said, calling Heather a “loser” who betrayed her for publicity.

“She would never say anything to my face. She would only say that on the radio,” she added. “She would never, 'cause she’s f—king scared and she should be. Now she should really be scared.”’

Handler continued on her rant: “She's such a dirty... what a loser. I heard that, I didn't even listen to the whole thing because I was like: this is so stupid…You can’t be scared to be at work, this isn't a concentration camp. You should quit then. Go quit.”

McDonald said she “100 percent lived in fear” on the Allegedly with Theo Von & Matthew Cole Weiss podcast.

“I don’t agree with how she treats relationships in her life,” she said. “I think she’s missing out and I think she’s missing out by dumping people. I think it’s a shame. You don’t have to cut someone out completely. That’s now how I live my life.”
