Mya and Donny Osmond are ready to square-off against each other and Kelly Osbourne on Monday's finale of "Dancing with the Stars."
"We've been working for three months for this night... even last night, we were at the studio with our professional partners, working our butts off," Osmond, 52, said on Ryan Seacrest's KIIS-FM radio show Monday morning.
Mya, 30, who also appeared on the show, said she's been working so hard for the ABC hit, she's practically moved into her rehearsal space.
"I bought a bed for the studio just so that we can power nap," Mya admitted. "It's definitely helped and paid off." Donny adds, "It will be nice to get back to our lives, because it's been nothing but dancing. I wake up in the middle of the night dancing in my bed."
The finalists will perform four dances this week, but it's not the added choreography that's stressing out Osmond -- it's his wardrobe.
"You know, I had that fiasco last week, a wardrobe malfunction where I tripped all over Kym's dress... we just hope everything is executed to plan."
Mya fears that she'll fail to live up to the expectations set by herself and judge Len Goodman.
"Len wants me to be fierce in the paso doble, which is very barbarian. He says, 'If you do not bring the sharpness on your first main number, I will not give you a 10. You have to bring the fire and connect with your partner and be very sharp and crisp. Period.'"
One judge Osmond isn't worrying about? Bruno Tonioli, with whom he shared a smooch earlier in the season.
"When I gave Bruno that kiss, I don't know what came over me, but it established such an interesting dynamic between us two," he said.
