Video: Kelly Osbourne and Mya: Our Worst DWTS Wardrobe Malfunctions Ever!

With the Dancing With the Stars finale one week away, it's not the judges' comments Kelly Osbourne and Mya are remembering most about their experience on the show -- it's their bumps and bruises!

"This competition is definitely a sport and I have a newfound respect for [dancers]," Mya, 30, tells Usmagazine.com in an exclusive video interview. (Watch a clip above) "I have pulled a back muscle, a groin muscle and some other things I'm not going to talk about. During tango week, I had 27 bruises!"

Agrees Osbourne: "The list of injuries is endless! What we do every Monday in the 'red room' when we have our costume on for dress rehearsal is [compare] who has the most bruises," she says. "Usually it's Mya."

Many of the girls' battle wounds have come as a result of wardrobe malfunctions.

"The worst thing I ever did on this show was doing a slide between someone's legs in my costume," Osbourne, 25, tells Us. "I had a wedgie and when my butt hit the floor, it gave me a burn mark! I was in the worst pain ever, and of course it was when I was trying to show off!"

While Osbourne's clothes call was obvious, Mya says her biggest blunder happened away from the ABC cameras.

"I definitely had a wardrobe malfunction on live TV, but thankfully no one saw it. During our team paso [doble], my entire dress ripped and I slipped on it during the choreography. Thank God the camera wasn't on me!" the singer/actress says. "I ran backstage and asked if anyone had scissors, a knife or a box cutter to cut the wire that got [tangled] in my dress. One guy had a pocket knife and cut it for me. I was back on stage in time for my solo!"
