Joanna Krupa may be hot stuff on Dancing With the Stars, but that doesn't mean things are just as steamy for her in the bedroom.

"Dancing With the Stars definitely hasn't helped my sex life," Krupa told us earlier today. "I have no time for anything except rehearsal. When I get home from rehearsals, I don't want to be bothered. Cuddling is enough for me. I'm mentally and physically exhausted, so my fiancé [businessman Romain Zago] will just have to wait."

So how's Zago handling the dry spell?

Krupa insists he's alright with it because he's focused on the dance floor, too. "He's stressing about the competition more than I am," she said. "He's always smoking outside my trailer after rehearsals. I'm like, 'What the heck? You don't smoke!' "

Sex talk aside, Krupa is relieved to have her flu-stricken dancing partner Derek Hough back. "He's still coughing a little bit, but he's definitely feeling much better," Krupa said. "I've actually had a cold, so we're both kind of under the weather."

But thankfully, Krupa assures us health will not affect her next performance: "Once you're on camera, you kind of forget about how you're feeling."
