Lauren Bernat, the “Wii Fit” hula girl, has been seen doing the hula in her underwear nearly 4 million times on YouTube since May 25. Yesterday afternoon, she came to MTV’s headquarters in New York all the way from Miami, Florida with her mischievous boyfriend Giovanny Gutierrez to appear on TRL.

Check out a short clip and photos of Bernat in action during the show. And sorry, fellas — she kept her pants on. [UPDATE: Read the extended interview with "Wii Fit girl" here.]
