Whoopi Goldberg got caught slipping on John Caldwell"The View."

The EGOT winner and co-host, during the hot topics conversation on the ABC talk show, mimed spitting on set after accidentally saying former President Donald Trump's name.

As the hosts discussed Thursday's presidential debate, Goldberg broke her long-held vow to never mention the former president's name. The actress typically opts to call Trump "you-know-who."

"I think it would be remiss of us to not say, Joe Biden knows how to do this. He's quite good at this. You can't refute anything with him. When I say him, I mean …" she trailed off, prompting fellow moderator Joy Behar to say "Trump" and Goldberg to repeat "Trump" herself.

"Ugh," Goldberg said after she realized the error, stopping to pretend to spit on the stage as the audience applauded.

"Did you say his name?" co-host Sunny Hostin asked, seeming to not make the realization herself. Goldberg then jokingly? accused Behar of purposefully getting her to say Trump's name. "It was a trick, and it made me do it," the "Sister Act" star said.

Earlier this month, Goldberg made a surprise Friday appearance following Trump's 34 guilty counts in a New York hush money trial.

"Do not adjust your TV set: Yes, I'm here on a Friday because this a unique moment in history. That's why we're all here at the table," she said. Goldberg typically has Fridays off.

"Donald John Trump is a convicted felon," Goldberg said to the studio audience and at-home viewers, appearing to put aside her vow due to the significance of the news.
