SABRINA BRYAN talks about HELIO CASTRONEVES' break-up with his girlfriend as we go behind the scenes with her and her fellow dancers DREW LACHEY, DEREK HOUGH and CHERYL BURKE for the first day of rehearsals for "Soft Scrub® Presents Dancing with the Stars -- The Tour," kicking off at the Key Arena in Seattle, WA, on December 18.

"It is so nice to jump into the rehearsals and get to know other dancers who are part of 'Dancing with the Stars' and some of the other stars," says SABRINA BRYAN, who will also be touring with MARIE OSMOND, JOEY LAWRENCE, WAYNE NEWTON and MONIQUE COLEMAN.

Sabrina will be partnered with MARK BALLAS, who is recovering from surgery, but she says, "We are going to have to tweak things a little bit here and there. We are making it work."

Plan B, if Mark's injuries should prevent him from dancing, is for DEREK HOUGH to replace him.

"Mark is my best friend," say Derek, who is in the band ALMOST AMY with Mark. "He is like my brother. I am going to step into his routines, but I am more excited about Mark getting back on the floor."

Mark isn't the only one with an injury. DREW LACHEY, former "Dancing with the Stars" champ, is rehearsing with a bum toe.

"I don't know if it is bruised or just messed up from my years of dancing now," he says. "You get little aches and pains, but it is okay."
