Last night (March 17) saw the premiere of the 18th season of 'Dancing With the Stars,' with Jason Derulo serving as the musical guest and Cody Simpson and James Maslow of Big Time Rush making their dancing debuts. How did it go?

Well, Derulo brought an explosive rendition of his latest hit 'Talk Dirty' to the stage while the show's troupe bumped and grinded throughout his routine and the song. It was sexy and saucy, especially when Derulo's silvery jacket came undone and showed off his washboard abs. But that's customary with Derulo. He sizzles and last night was no different. He's got the voice and the moves.

Simpson also danced the Cha Cha to Pitbull and Kesha's 'Timber' during his debut. The judges liked his cool moves and the ebullience of his youth, but they also told him to work on his bottom half. Hey, it was just the first ep of the season.

Big Time Rush star Maslow and his partner Peta did the foxtrot to One Direction's 'Story of My Life' and they looked like a couple as they glided across the floor. The judges liked it but felt the boy bander's footwork needed to be more precise. Again, it was the first night and nerves were likely high.

Both pop gents impressed us as viewers.

Will Simpson and Maslow survive to dance another week? Stay tuned.
