Welcome to the Dancing with the Stars quarterfinals.

Also known as: the Mya and Dmitry show!

We finally witnessed the first perfect score of season nine last night, as the favorite strutted her stuff with one Ballroom routine and one Lation performance. She clearly separated herself from the pack.

Relive this week's performance show now, via our recap of scores and dances. Who was your favorite? Who do you think should go home tonight?

Here's a rundown of last night's leaderboard, based on two dances/couple:

• Mya and Dmitry Chaplin: 59
• Joanna Krupa and Derek Hough: 52
• Kelly Osbourne and Louis van Amstel: 51
• Aaron Carter and Karina Smirnoff: 50
• Donny Osmond and Kym Johnson: 50

Tonight, Michael Bublé and Susan Boyle will sing for the audience.
