"Dancing with the Stars: All-Star" contestant, and season one winner, Kelly Monaco, had a tough dance to perform last night, but nonetheless, she still got pretty steamy with her partner Valentin Chmerkovskiy, and rumors of a romance between the two are not stopping anytime soon.

On Monday night, Oct. 15, Monaco, 36, and Chmerkovskiy, 26, had to perform a contemporary routine picked for them by fellow dancers Cheryl Burke and her partner Emmitt Smith. A contemporary routine has never been performed before on "DWTS" and even the judges agreed that they had the most challenging dance to perform. 

"I personally told her to (expletive) off for giving me (contemporary)," Monacotold The Clicker, about Burke's decision to give her a contemporary routine. "I'd never even heard of it! I don't watch 'So You Think You Can Dance.' ... I was like, 'This isn't the show I signed up for!' I didn't know I'd be doing this!" 

However, the final performance to a Coldplay tune got rave reviews from the judges and made Carrie Ann Inaba slightly tear. But did she and Chmerkovskiy kiss during their dance?

To many viewers, it might have seemed that way. Especially because the two have become extremely close, and touchy-feely, with each other. Their contemporary routine was full of passion (the idea behind the number was for them to act like lovers) and even one judge said the pair had a chemistry and are in synch like no other team. A few times throughout the "DWTS" episode, they were nose-to-nose on camera, both during their dance and before it. Also, at the end of their routine, Monaco, who was on her partner's shoulders, slowly slid down in front of Chmerkovskiy and again, though her hair covers their faces, it looks like they may have kissed. 

While the two of them refuse to admit to any romantic relationship ("no labels," Chmerkovskiy said), Monaco said last night that her partner is "breaking down my walls." The two snuggled in each other's arms throughout the show and when Monaco got emotional talking about the "DWTS" experience before receiving her scores, she may have even brought her partner to tears: Chmerkovskiy clearly wiped his eyes after she finished talking. 

During the routine she said she felt, "really raw and emotional and accurate and truthful. Val is helping me learn how to trust again."
