They may have gotten the lowest scores on Monday night's premiere of Dancing with the Stars, but off the dance floor Lacey Schwimmer and Mike Catherwood are winning in love, Breaking Celebrity News has learned exclusively -- even after the network warned the dancing duo to turn down the heat!

"The network asked them to tone down the sexual undertones," a source close to the pair told Breaking Celebrity News exclusively. "They know there is a spark there -- everyone is talking about their amazing chemistry."

DWTS veteran and hoofing hottie Lacey teamed up with Loveline's "Psycho" Mike for the foxtrot on the season 12 premiere which landed them the lowest scores of the night.

But, although they're still perfecting their moves in the ballroom, they don't need any help off-camera it seems.

The twosome haven't been shy about their flirty feelings for each other, with Mike joking "the best part about the routine was grabbing her butt," said our source, and Lacey telling Breaking Celebrity News: "we would make a great couple" and admitting she seen "every part of his body."

And their attention for each other is definitely getting the network's attention, if not the judges' votes.

"They basically told them to cool it with the sexual tension," our source said. "But they both just laughed about it."

Lacey told Breaking Celebrity News that Mike does have a girlfriend, but our source says that he and his girlfriend are "on the rocks."
