'DWTS': Jennifer Grey Bringing 'Fireworks & Rock-n-Roll'

"Dancing with the Stars" frontrunners Jennifer Grey and partner Derek Hough are bringing the heat Monday night with their Paso Doble routine.

"Our whole night is gonna be rock-n-roll," Hough told "Extra's" Mario Lopez. "It's gonna be fireworks, fire, pyro. It's gonna be a lot of fun. A good show."

Going into week six of the competition, Jennifer said her husband and daughter have been responding well, despite the many hours she's spending in rehearsal.

"My daughter's in a great place. My husband's cooking the meals, taking her to school, doing the homework," the "Dirty Dancing" star said. "It's a beautiful thing."

While most of the celebs are happy to burn the calories, Grey said she's struggling to keep the weight on.

"I actually feel like I'm trying to keep weight on, because I didn't have anything to lose to begin with," she explained. "I really have to stuff the carbs and protein."

Catch all the dancing action tonight at 8:00 PM PDT on ABC.
