For many celebrities, social media is a place to give fans a glimpse into their lives away from the spotlight and this includes sharing images of their children. Some even grace red carpets with their famous parents or take to the stage with them - think Blue Ivy.

From Hollywood stars such as Blake Lively and Ryan Reynolds, to Mila Kunis and Ashton Kutcher, these are the rarest photos of the kids of stars today.
