Even after 18 seasons with “Dancing With The Stars,” professional ballroom dancer Cheryl Burke says there’s one dance move she hasn’t quite mastered yet.

In an interview with HuffPost Live on Wednesday, Burke revealed that for the upcoming finale episode of “I Can Do That,” she was tasked with performing signature choreography from the Dallas Cowboys cheerleaders, pushing her flexibility to the limit.

“Even as a dancer I can’t do the splits, and they’re famous for that drop split,” she told host Nancy Redd. “Yeah, my back is super flexible, but I’ve never been able to do a drop split. That was a lot of pain.”

Watch Burke attempt to nail the drop split in next week’s finale episode of the NBC show, which airs on Tuesday at 10 pm ET.
