Jessica Simpson Shares Photo Of Baby Ace Growing Fascinated With An Ottoman

Jessica Simpson Instagram

On Sunday, July 27, Jessica Simpson shared the following photo of her adorable son Ace, playing with both CaCee Cobb's son Rocco and what appears to be a most enchanting ottoman.

At 13 months, Ace did an impressive job of standing up to play with the fascinating beaded material.

As People notes, Cobb and Simpson have formed a friendship between their children in recent months that has at least once been called a "baby bromance."

Simpson, who married Eric Johnson earlier this month, has turned her Instagram into a lovely family album, featuring her babies and also other babies. Here she is with a particularly cute one named Wyatt.
