Madonna couldn't be more grateful to have her kids by her side. On Instagram, the singer honored her children by sharing behind-the-scenes photos of them from her ‘Celebration’ tour. The past few months, Madge’s kids, Estere, David, Stella and Mercy, have joined their mom on stage. In the post, Madonna reveals she had a 'near-death experience' while rehearsing for the show, but her kids 'never stopped' cheering her on and supporting her.
