Casper Smart sure knows how to get a party started!

Mentoring the dancers on Wednesday's episode of MTV's America's Best Dance Crew, choreographer Smart, 25, just so happens to be an expert on this week's theme: the music of Jennifer Lopez.

The six remaining dance crews -- "8 Flavahz," "Collizion," "Elektrolytes," "Fanny Pak," "Mos Wanted" and "RNG" -- will groove to songs made famous by Smart's girlfriend, 42, in an effort to advance to the next round.

To get the crowd pumped for Jennifer Lopez Week on ABDC, Smart -- who will soon choreograph his love's world concert tour -- leads a Lopez dance-off as MTV's Pauly D spins her hit "Get Right."

Watch the hilarious dance-off -- even ABDC judge J.C. Chasez gets in on the fun! -- in the clip above now before America's Best Dance Crew airs Wednesday at 10 p.m. (EST) on MTV.
