During rehearsals for 'Dancing With the Stars' Week 8, James Maslow got a little visit from the boys of Big Time Rush. Kendall Schmidt, Carlos Pena, Jr. and Logan Henderson all stopped by rehearsals to watch Maslow and Peta Murgatroyd rehearse this week's number, which was the Viennese Waltz.

"You guys have chemistry like a married couple," Kendall laughed, watching James and Peta dance together. "Are you guys like dating or something?"

To their credit, James and Peta would only give each other a knowing look, which had the guys of BTR roaring with laughter.

Of course, Kendall was absolutely right: The pair do have amazing chemistry together, which was more evident than ever last night as they gallantly glided across the dance floor, dancing the Viennese Waltz. Not only did Peta look flawless in her pink, feathery gown, but James looked like the perfect gentleman, donning a gray suit with light pink tie that perfectly matched Peta's dress. And their routine was well praised, with guest judge Abby Lee Miller noting that it was James' job to make Peta look incredible, and he did so with ease.

Still, James and Peta came into the bottom three, with a score of 36 points (tying with Candace Cameron Bure and Mark Ballas and Meryl Davis and Maks Chmerkovskiy.) However, they scored the highest of all the celebrity dance duels, garnering 39 points with Amy Purdy and Derek Hough.

Ultimately, James and Peta are safe for another round as they head into the semi-finals this week.
