This is almost too much adorableness for one photo.

On Saturday, Jessica Simpson shared a new photo of son Ace on Instagram -- and he's got a celebrity baby buddy!

That other cute tot on the rug with little Ace Knute is Donald Faison's son with Cacee Cobb, who just happens to be Jess' best friend. Rocco was born just two months after Simpson's second child.

"BFF's in the making! @caceecobb #ACEANDROCCO," Jessica captioned the pic.

Rocco is Cobb's first child with Faison, who has four kids from previous relationships.

We hope to see more of these two hanging out in the future -- they make one ridiculously cute pair!

Check out more photos Jessica has shared of Ace and her equally precious daughter Maxwell in the gallery above. Simpson and fiance Eric Johnson definitely have one good looking family!
