Some of season 10 contestants of 'Dancing with the Stars' have been snapped hard at work on the dance floor, preparing for Monday, March 8 performance with their professional partners.

First photos from season 10 of "Dancing with the Stars" have been making their rounds. Taken by ABC photographer Rick Powell in the dance studio, most of them give a sneak peek at the six-hour rehearsal Nicole Scherzinger and Jake Pavelka had with their professional dancing partners on Monday night, March 1.

The lead singer of The Pussycat Dolls came to the studio dressed in some green-colored designer sweats. Joining season 7 champ Derek Hough for the training, the 31-year-old showed that she's all work. She reportedly skipped the basics and was quick to move on with some Tango moves.

"The Bachelor" star Pavelka, on the other hand, showed up for the rehearsal with partner Chelsie Hightower in jeans and a long sleeve shirt, before changing his outfit into a more comfortable T-shirt and shorts. In some of the pictures, he is snapped practicing his fancy footwork. One in particular, however, sees Hightower shows him how to stretch out his leg muscles.

Beside the two celebrities, another contestant captured on camera during the rehearsal is astronaut Buzz Aldrin. With the assistance from dancing partner Ashly Costa, the second person to set foot on the Moon is seen learning how to glide in his loafers.

All the 11 contestants of "Dancing with the Stars" are expected to showcase their Viennese Waltz and Cha Cha routines when season 10 makes its debut on Monday, March 22. The two-hour premiere will be kicked off at 8 P.M. on ABC.
