Page Six reports that Mario and his “Dancing With the Stars” partner Karina Smirnoff might be doing the tango off camera, too.

Karina Smirnoff might have two partners off the dance floor. The shapely brunette has stepped out publicly with her former dance partner, Mario Lopez, but was also recently spotted kissing her current one, R&B singer Mario, at the Four Seasons in Los Angeles. “They were making out by the valet with their hands all over each other, and he was whispering in her ear,” said our source. “It was around midnight, so there weren’t many people around.” The two then got in the same car and drove off together with Mario at the wheel. Karina’s rep denied the kiss, saying she and Mario have a “professional working relationship.”

Sexy as they might look on the dance floor, we don’t believe this one. You?

Mario will be hoofin’ it on the new season of “Dancing With the Stars.” Finally, a reason to watch! Other stars in the line up include: NFL star Jason Taylor, actress Marlee Matlin, actor Steve Guttenberg, Priscilla Presley, tennis champ Monica Seles and Olympic skater Kristi Yamaguchi.
