Hollywood Reporter has a clip of the opening number for America's Best Dance Crew's new season. In it, the five crews competing that night dance to Britney Spears' music. The crews: Fanny Pak, Step Boys, Irratik, Mix'd Elements, and 8 Flavahz. The playlist includes:“I Wanna Go,” “3,” “Till The World Ends,” “Hold It Against Me,” “If You Seek Amy” and “Womanizer.” Can't wait! Thanks for the tip, grOOvealOOse and illGetaNameLater!
