Video! Mario Lopez Dances Up a Sweat with Kirstie Alley

"Extra's" Mario Lopez whisked Kirstie Alley to the dance floor and worked up a sweat in celebration of Alley's "100 Days of Dance" campaign to promote a healthy lifestyle.

Kirstie, 61, a former "Dancing with the Stars" finalist, has kept off the 100 pounds she lost, and explained why she started "100 Days of Dance." "I had so many people on Twitter saying they wished they could do 'Dancing with the Non-Stars.' I wanted to give everybody an opportunity to just move and have fun at least for the first part of the year."

The actress revealed she will be dancing with "a whole lineup of guys," including her good pal, John Travolta. "Yeah, he'll dance with me."

When Lopez suggested Kirstie culminate her one hundred days at The Grove with "Extra," Alley squealed, "I'd love to end the rest of my life with you, Mario!"
