The first cast addition for the eighth season of Dancing with the Stars has been announced... and it's not terribly exciting.

During a segment on The Bonnie Hunt Show, Donnie Osmond appeared with sister Marie - who starred on the show's fifth edition - and let slip that he was officially on board for the next installment, which premieres in March.

"I guess I am making an announcement. I'll say I am seriously considering doing it, let's put it that way," Donne said, laughing and adding: "I guess I just let the cat out of the bag."

Are you excited to see Donnie Osmond on Dancing with the Stars?

** UPDATE: Osmond has now told Entertainment Tonight that he will not be joining the show this spring.

"If there was an offer on the table, I'd do it in the fall. I would make room for it. Absolutely!"
