Taking after their BFF moms!

Jessica Simpson posted an adorable picture of her son Ace playing with CaCee Cobb's baby boy Rocco on Sunday, July 27.

"Roc and Ace @caceecobb @donald_aison," the 34-year-old wrote.

The little guys appeared to be standing up for the adorable snapshot as they held onto an ottoman in a living room. Ace, 13 months, wore a grey T-shirt for the photo op, showing off his adorable pouty lips and blonde locks. A grinning Rocco, 11 months, donned a mustard yellow top while playing with a cream-colored blanket.

Simpson, who tied the knot with fiance Eric Johnson on July 5, often posts pictures of the boys via social media. In February, she shared a black and white photo of them crawling. Three months later, Ace and Donald Faison's son bonded while taking a bath over the Easter weekend.

Despite Ace appearing to have a ball with his pal, it appears the fashion mogul has no plans to give Ace and 2-year-old daughter Maxwell another sibling. "I love you Jack," she wrote via Instagram on July 20, along with a picture of her designer pal Kathryn Sykora's boy, "but I do not want another!!"
