During a recent taping of The Bonnie Hunt Show, Donny Osmond “let slip” that he is considering following in the footsteps of sister Marie by appearing on the hit ABC show Dancing With The Stars, PEOPLE.com reported on Monday.

“I guess I am making an announcement: I’ll say I am seriously considering doing it, let’s put it that way,” Donny told Bonnie. “I guess I just let the cat out of the bag.”

“I can’t let my sister upstage me,” he continued. “Besides, who do you think taught her how to dance?”

Donny added, “It is going to be very difficult because I am going to be doing [our Las Vegas show] on top of doing ‘Dancing with the Stars.’”

“I just want to see him in stretchy pants.”

Donny and Marie’s appearance on The Bonnie Hunt Show is scheduled to air this Tuesday.
