Has "Dancing with the Stars" become a bigger phenomenon than "American Idol"? We can't say for certain, but one thing is for sure—thanks to Helio Castroneves, "Dancing" is gaining ground.

As album sales of last season's "Idol" winner, Jordin Sparks, tanked, searches on Helio, the recent "Dancing" champ, surged 467%. Helio's rhythm and charisma played a part, but searchers were most interested in his love life.

To wit, queries on his dance partner, the fetching Julianne Hough, surged 456%. Queries on "helio and julianne dating" and "helio julianne girlfriend" also posted big gains. Clearly, fans are wondering if the pair are more than just platonic partners.

But let's not forget about Aliette Vazquez, Helio's ex-fiancee. Less than 24 hours after Helio won the Dancing trophy, his longtime lady called off their engagement. Is Julianne the reason? We have no idea, but the rumors have been good for Dancing's buzz.
