Heather McDonald has more than a few choice words for her former pal Chelsea Handler.

“It was hard. Never being promoted … If a new writer came on, they got the same thing as I did. That part bugged me,” she told Allegedly with Theo Von & Matthew Cole Weiss.

But that's not even the worst of it! According to Heather, when the show ended Chelsea cut ties with her.

“My relationship with Chelsea ended," she said. “I don’t agree with how she treats relationships in her life. 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.”

“I think she’s really funny and when you’re in your life and her friend it’s the greatest thing … It’s the best thing ever. It’s so much fun. She laughs at you. And that’s what’s sad,” she added. “She makes you feel so special until you’re not.”
