John Legend just proved that his daughter Esti is his No. 1 fan. Legend, 46, took to Instagram on Sunday, September 14, to share a video of Esti, 2, and sons Miles, 7, and Wren, 2, dancing in a living room to his performance of "Glory" at the Grace for the World concert at St. Peter's Square in Vatican City, which is now streaming on Disney+. While Miles stood on the couch and Wren leaned against the coffee table, Esti stood right in front of the TV, clapping her hands and jumping up and down. The toddler then started bouncing on the couch.
