Joanna Krupa is hot and we're excited to see her pose in Playboy next month.

That's about the only positive piece of news we can conjure up from last night's Dancing with the Stars performance show, as well as from season nine in general.

It's baffling why the competition chose to include more celebrities than ever for this edition, considering the Z-listers it had to reach for. Seriously, is anyone out there psyched over Mark Dacascos this season? Were you at any point?

This week's installment featured an array of solo dances and two group routines. None stood out, though Derek Hough and Krupa (pictured) earned the highest combined score.

Let's take a look at last night's leaderboard:

• Joanna Krupa and Derek Hough: 55
• Aaron Carter and Karina Smirnoff: 53
• Donny Osmond and Kym Johnson: 52
• Kelly Osbourne and Louis van Amstel: 52
• Mya and Dmitry Chaplin: 49
• Michael Irvin and Anna Demidova: 47
• Mark Dacascos and Anna Trebunskaya: 43
