Derek Hough can't stop laughing about partner Lil' Kim's wardrobe malfunction on Monday's Dancing With the Stars.

"She desperately tried to pull a Janet Jackson!" he told after she had some trouble with her top at the end of a jive. (The nearly X-rated moment was edited out by the time the show was rebroadcast on the West Coast.)

"Don't say that!" Kim interrupted. "That's a whole other show! I'd have to get paid a lot a lot of money!"

Hough added that host Tom Bergeron "covered up the girls, that is for sure."

The malfunction didn't seem to bother the judges: Kim and Hough earned the night's best score, a 28 out of a 30.

Hough still can't get over how good she looked.

"When she came out, I'm not going to say what I said, but...." he began.

"No, say it - I like to hear it!!!" Kim interjected.

"I was like, 'Yeah, I'd hit that!'" he teased.

Joked Kim, "I saw him checking me out!"

Kidding aside, Hough is still dating former contestant Shannon Elizabeth.

"Shannon, Derek's girlfriend, is so amazing," Kim told Us. "She keeps him calm at practice, so that is a good thing for me!"

Said Hough, "Shannon is always on hand, taking lots of pictures, bringing

snacks and keeping our spirits up in rehearsals! She's the best."
