Watch: Michelle Obama Turns it Up in Viral Vine

Fitness junkie first lady Michelle Obama is turnin' it up (letting loose) and is burnin' calories doing it. She's also going viral in a Vine video.

Here's what went down. In an #AskTheFirstLady segment, Barack Obama impersonator Imman Crosson, or @AlphaCat, asked Obama, "How many calories do you burn every time you 'turn up'?!"

Her six-second response, posted on the White House Vine account?

She may just be the next Beyonce. It's a take on DJ Snake and Lil Jon's "Turn Down for What." Mrs. Obama is known for her commitment to childhood health. Her "Let's Move" campaign aims to "solve the epidemic of childhood obesity within a generation."

Coolest first lady ever? Or a marketing genius? Weigh-in.
