Marie Osmond 'chipped off a piece' of her kneecap when she fell on stage during performance

Marie Osmond is the embodiment of "the show must go on."

The "Talk" co-host opened up about falling on stage during one of her Las Vegas "Donny and Marie" residency performances last week, breaking her knee in the process.

Video from the concert shows Osmond telling her brother, "I can't walk … I think I broke my knee. … I did it once before and I just did it a second time."

"It’s underneath the kneecap, I chipped off a piece," Osmond said. "So I probably won't be dancing a lot but I can sing."

She assured fans that regardless of her injury, she would be present during the last week of shows for "Donny and Marie."

"This is the last week of shows at the Flamingo. So for those of you that have bought tickets for that last week, I will be there," Osmond said.

"Donny was so sweet. He said, 'Marie, I can handle the last week,’ and I said, 'I think they want to see Donny and Marie,' " she added.

"I’m always okay, and you know, it’s just interesting that it would be so close together. I’ve never fallen before," Osmond said. "I think maybe the knee was a little bit not as strong. I probably should have been wearing my brace. But as I made that turn my boot stuck on the floor and then I wasn’t able to turn and I just went down."

This isn't the first time Osmond has tumbled on stage. The performer fell in September and badly bruised her knees.

The showbiz veteran didn't let her injury interfere with her hosting duties, because she made it to California in time to film.

"Look at my knees," she said from her "Talk" dressing room, where she iced her bruises. "I actually did this at the Flamingo dancing with Donny last night, but I'm going to be there tonight! Yes I am. I got to get on a plane."

Osmond is juggling her duties at the CBS daytime talk show and her Vegas show until the end of this week, when the singing siblings' residency ends after 11 years.
