Cheryl Burke and Drew Lachey were partners on Dancing with the Stars. They are not partners between the sheets, however.

The pair is being forced to deny tabloid reports that more than just foxtrotting was going on during their season together.

Cheryl Burke and Drew Lachey captured the Dancing with the Stars trophy. But the relationship was about dancing, not sexing each other up, both sides say.

A report claiming the couple had an affair are "completely false and cannot be further from the truth," a rep for Lachey said, while a rep for Burke adds:

"The story that Cheryl is involved with Drew Lachey started two years ago when they were partners on Dancing with the Stars. It wasn't true then and it isn't true now."

A source close to the show also called the report "untrue and irresponsible."
