AceShowbiz - Comedienne Kathy Griffin has revealed she and Ellen Degeneres are still not speaking after falling out over a Joan Rivers tribute show.

Griffin opened up about the drama during a show in Los Angeles last week, telling fans she tried to recruit the "Finding Dory" star for the special, but Ellen refused to perform because she was not a fan of acid-tongued Rivers.

"One of the things that really hurt Joan, and we talked about it at our last meal together, was that Ellen always shunned her and Ellen thought she was vulgar and not funny," Griffin said, according to The Huffington Post, revealing she never thought DeGeneres would snub her pal after her death in 2014.

"I just called her and I just said, 'Look, woman to woman, comic to comic, I think you need to let go of your hatred for Joan Rivers. She's passed away, just do a f**king tribute, be cool'."

DeGeneres refused, telling Griffin she found Rivers "mean", and the two comics argued over the phone.

"We had a fight in which I used inflammatory words like, 'Look, you f**king untalented hack...,' Griffin recalled. "You know when you're fighting with someone and you can kind of laugh at a point? Yeah, not that day."

Griffin later texted DeGeneres but the former Oscars host didn't respond.
