Rosie O’Donnell name-dropped Keanu Reeves as “one of [her] worst” talk show guests.

While the former “Rosie O’Donnell Show” host did not mean to throw the A-list actor “under the bus” during her “Sam Pang Tonight” appearance Monday evening, she detailed why Reeves is “not good” in on-air interviews.

“I love the guy,” the 63-year-old clarified of their 1997 sit-down interview. “He’s so sweet, he looks gorgeous, I love all his movies, but he would not answer a question.”

“I’d say, ‘So, Keanu, how’s it going? How are you feeling?’ [He’d respond] ‘Good.’ We were live. We couldn’t re-tape,” O’Donnell recalled.

“I finally said after three minutes, ‘You know, Keanu, it is a talk show. You have to talk.’”

O’Donnell, who doubled down on Reeves, 61, being “a lovely man and a good-hearted guy,” noted that the “John Wick” star “did come back” onto her show in 2001.

“So he got the hang of it,” the Emmy winner quipped.

During Reeves’ first appearance on O’Donnell’s eponymous show, she did, in fact, call him out about not opening up enough.

When the musician laughed at one of O’Donnell’s questions, she quipped, “Sorry, but you know it’s a talk show. We’ve got to ask questions.”

The former “View” host went on to ask, “You don’t do a lot of these shows do you? Do you hate them?”

“I’m not comfortable with them, but they’re fun. It’s alright,” Reeves replied, to which O’Donnell offered him a snack or toy.

YouTube users praised O’Donnell for putting the “introverted” star “at ease” during the rest of the 10-minute chat.

One wrote, “I like how [she] changed her strategy after knowing Keanu was uncomfortable being asked that much.”
