Engaged Bachelor star Sean Lowe and his Dancing With the Stars partner Peta Murgatroyd have been heating up the dance floor with their moves. And during week three rehearsals, Lowe put a few moves on Murgatroyd.

Lowe surprised Murgatroyd by giving her a red-rose corsage for the prom themed routine. "I want to give you the best prom that you've ever had because I know your first prom wasn't the best."

She said her prom was awful because her date had a girlfriend. Lowe joked, "This time your date has a fiancé, that's even worse."

Their last performance on Monday night, a Cha Cha to the YMCA, was deemed Lowe's best routine yet by judge Len Goodman.

In an interview in the April issue of Life & Style, Murgatroyd said she and Lowe have great chemisty. "I think he's very sexy. We have the perfect relationship. We look like a great couple together - Ken and Barbie!"

Lowe said of Murgatroyd, "Look at her - that has to count for votes."

He added, "My relationship with her continues to evolve and I feel more and more comfortable each day as we dance."

Lowe and Murgatroyd scored a 21 for their Monday performance. As they continue in the competition, Murgatroyd told the magazine she keeps Lowe's fiancé, Catherine Giudici, in the back of her mind when choregraphing and rehearsing.

However, she did also tell the magazine of Lowe, "I couldn't think of a better person to be stuck in a room with, sweating. I think we have the most fun out of any couple."

Murgatroyd said of their routines, "I'm very passionate about my dancing and when it's a sexy thing, I go all in and I have to think, 'Maybe I shouldn't go that far with this partner.'"
