Beyonce surprised students at PS 161 in Harlem as part of First Lady Michelle Obama's 'Let's Move' initiative to fight childhood obesity.
Students at a Harlem public school working out to a Beyoncé song got a big surprise when the superstar walked in and joined them.
About 85 students at P.S. 161 were in the middle of a choreographed routine Tuesday to "Single Ladies,'' a song adapted from Beyoncé's hit "Get Me Bodied.''
The singer joined in wearing stiletto heels and a T-shirt emblazoned with "Let's Move.''
Thirteen-year-old Aisha Collier gushed "she's so beautiful.'' She told the New York Post she messed up a little when Beyoncé first arrived but then got back into it and continued to dance and have fun.
The children were participating in a national simulcast of "Let's Move Flash Workout.'' It's part of first lady Michelle Obama's fitness campaign.
The official music video for "Move Your Body" is below. Find the instructional video and learn more about the flash workout in our previous post, "NYC Schools Can Now Register for Beyonce Flash Workout."
