People.com reports that Donny let slip during a taping of "The Bonnie Hunt Show" that he is considering following in the footsteps of sister Marie on the hit ABC show.

"I guess I am making an announcement: I'll say I am seriously considering doing it, let's put it that way," said Donny after Bonnie asked him if he'd do the show, adding, "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?"

"That not fair!" cried Marie, who was sitting beside him. "The men do half the work."

"That's why I'm doing it, baby," Donny responded. "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," quipped Marie.

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