Helio Castroneves threw a swingin' party at Sunset Towers in LA last night in celebration of his big Dancing With the Stars win. Of course, a Miami-based sponsor was in on the act in the form of LEBLON, whose own team member Daniella did a samba showcase with Castroneves. But all eyes were on the speed racer and his dance partner, Julianne Hough. When asked if they were officially out as a couple, they denied all. They did, however, bust out with a couple of dance moves. After all the hype, Helio headed back to Miami for some much needed downtime--alone, as far as we know.
