LOS ANGELES -- Marie Osmond fainted onstage during the live broadcast on WSB-TV Channel 2 Monday of "Dancing with the Stars" but quickly recovered.

Osmond and her partner, dancer Jonathan Roberts, the first performers of the evening, had just finished an energetic samba and were listening to comments from the show's judges when she suddenly toppled.

"She was laughing and then sank like a stone. ... Everyone froze," said ABC publicist Amy Astley. As the show cut to a commercial, Osmond started to rise and was helped by others, Astley said.

When the show resumed after the break, host Tom Bergeron told the studio audience and TV viewers that Osmond had fainted but was fine.

"I want to just quote her exactly. ... The first words out of her mouth when she saw us all leaning over her were, 'Oh, crap,"' Bergeron said. A backstage camera showed Osmond smiling and nodding.

The singer, who turned 48 on Oct. 13, was well enough to take part in the next segment, in which she and Roberts learned that judges Carrie Ann Inaba, Bruno Tonioli and Len Goodman had each awarded them seven out of 10 possible points.
