Cristian De La Fuente and Cheryl Burke reunited for a trip to Cheryl's hometown of San Francisco -- and they shot home movies for ET to show you!

The former "Dancing with the Stars" partners jumped on a jet for an exclusive class at Cheryl Burke Dance, which was attended by 200 invitees who are all learning how to tango, salsa or swing from their classes at the two-time "DWTS" champ's studio.

Cristian, who is well on his way to recovery from his arm surgery, jokes, "'Cause my arm is bad, you see the scar over there? I'm not carrying my luggage."

But that doesn't stop them from showing off the skill that took them to the Top 3 of the competition. "Just when I thought my dancing days were over, they're not over," Cristian continues. "I'm not only dancing, I'm also being a camera guy."

Then Cristian catches Cheryl in a candid moment. "Oh, I'm shiny, you see, no makeup," she points out. "We're going to rehearse, ET. This is no makeup 'cause it's live television. It's reality TV. It's for ET. It's the way things happen."

The crowd applauds as Cristian and Cheryl demonstrate the moves that made them famous. Then they're back at the airport, boarding a plane headed to San Diego for a dance competition.

"Once you do 'Dancing with the Stars,' you're attached to dancing forever," Cristian tells the cameras. "It's like once a Marine, always a Marine ... kind of the same thing with dancing."
