Apolo Ohno was crowned the winner of Dancing with the Stars’ fourth season earlier this week on his 25^th birthday. He and his lovely partner, 18 year old Julianne Hough, had a smoldering chemistry on the dance floor. Apolo admits that but insists that their relationship was “strictly professional.”

Fueling the speculation that the two are a couple is the fact that Julianne postponed her August wedding to former dancer Zach Wilson. Julianne told People a few weeks ago that “[Zach and I] are still together. We just want [more time] before we get married. It's all good!”

Zach himself told TV Guide that “I’ve been involved in ballroom a lot, so I know there has to be chemistry when you dance together. It doesn't mean that there’s any romance going on. And I know personally that there’s not, because I've been with them in rehearsals and I've gotten to know Apolo really well. He’s a really nice guy. So it doesn't bother me.”
