I had predicted that Donny Osmond would soon be heading to the 'DWTS' ballroom two seasons ago, judging by the longing looks he donned as his sister Marie kicked up her heels to the finals.

Well, seems Donny will be passo doble-ing sooner than we think.

On today's "Bonnie Hunt" show, he reveals (during an interview with his sister Marie) that he will be "busy doing 'Dancing with the Stars' on top of their Las Vegas show at Harrah's.

Donny Osmond will follow in his sister's dancing footsteps when he joins season 8's celebrity lineup on "Dancing with the Stars." AP

There you have it. Tune in today and hear the news for yourself.

Here's a transcript from the show, which was taped Monday, of the big reveal:

When asked by Bonnie if he would ever strut his moves on the dance floor, Donny smiled and said, "Well, I guess I am making an announcement. I'll say I am seriously considering doing it, let's put it that way."

Unable to keep the secret in, Donny added, "I guess I just let the cat out of the bag!" Donny said Marie, who competed on the fifth season of "Dancing" and also appeared on the Monday taping of the talk show, wasn't going to be the only Osmond in the "Dancing" spotlight.

"I can't let my sister upstage me. Besides, who do you think taught her how to dance?" he joked.

"That's not fair!" Marie said. "The men do half the work." "That's why I'm doing it, baby," Donny replied.

"It is going to be very difficult because I am going to be doing [the Osmonds' Las Vegas show] on top of doing 'Dancing with the Stars.'"

"Dancing With the Stars" returns March 9.
