Rosie O’Donnell has been trashing fellow comic Ellen DeGeneres by revealing new details about their decades-long fallout, and insiders say the shamed TV host is freaking out and squawking that she can’t catch a break.

Sources say that 63-year-old Rosie continues to rip into Ellen, 67, because she thinks the former talk show queen bee is a fraud.

Rosie recalled her friendship with Ellen flamed out after the voice of Disney’s Dory the fish blabbed on live TV that she wasn’t friendly with Rosie.

“That was, like, one of the most painful things that ever happened to me, in show business, in my life,” she confesses on an episode of Mamamia’s No Filter podcast. “I couldn’t believe it. I have photos of her holding my newborn babies. I knew her for 30 years.”

Rosie also said Ellen didn’t support her when she came out as gay during a comedy set in February 2002, but that she supported Ellen when she jumped outta the closet on her popular talk show in 1997.

“Instead of deciding to stand next to me and hold my hand, which is what I did to her, she did the opposite,” Rosie complains.

Says an insider, “It’s shocking to Ellen that Rosie is still dredging up the past and saying negative things about her.”

“Not too long ago, Rosie ripped Ellen by recalling the ‘weirdness’ in their relationship. Now she’s doing it again but with more force.”

As Globe has reported, Ellen ended her long-running talk show, The Ellen DeGeneres Show, in shame following 19 seasons in 2022 after staffers accused her of being nasty and demanding behind the scenes, and running a toxic workplace — and she’s now living in self-imposed exile in England with her actress wife, 52-year-old Portia de Rossi. (Ellen made an on-air apology to viewers and staff, saying things “happened here that never should have happened.”)

Meanwhile, Rosie moved to Dublin, Ireland, with her daughter Dakota following Donald Trump’s presidential win.

“Ellen wants peace and quiet in her life, but Rosie won’t let her have it. She thinks Rosie enjoys taking digs at her,” claims the insider. “She’s desperately trying to get a TV comeback off the ground, and it’s been hard, so this is the last thing she needs.”
