Selena Gomez and Mario Lopez Dance It Up for ‘Extra’ (PHOTOS)

Selena Gomez thought she was just going to be doing a little interview for Extra on Tuesday. Somehow though, Mario Lopez and the teen queen wound up cutting a rug and dancing the day away.

Lopez and Gomez filmed the segment at The Grove in Hollywood, and amidst a crowd of fans holding up cell phone cameras, Gomez flashed her million-dollar smile as Lopez whisked her into a dance.
