I ask that you keep him and our entire family in your prayers-Especially Danielle, Richard, Naomi & Dj and know that we've all been touched by our little Guardian Angel. His memory will forever live on in our thoughts and our hearts. May he now rest in peace in the arms of our Heavenly Father," Milian wrote, according to Us weekly.
