Michelle Obama surprised a group of students in Detroit while promoting her 'Becoming' book tour.

The students had gathered at the Motown Museum for a round table discussion on education. The talk was hosted by Detroit native, Keegan-Michael Key and Michelle's brother Craig Robinson.

The look on the students faces as the former first lady entered the room was priceless.

Most of the students had to do an immediate double take when she walked through the door. Michelle took some time to talk about how important the meeting was to her on twitter afterward.

The impact that being inside the Motown Museum must have stuck with Michelle after she left Detroit.

She connected with Motown Records to create a 'Becoming Motown' playlist.
