When Jessica Simpson married Eric Johnson on July 5, two of the guests were Jess's best friend CaCee Cobb and her husband, Scrubs actor Donald Faison. Jess was also a bridesmaid at CaCee's December 2012 wedding.

The families are very close, and when both Jessica and CaCee got pregnant within months of each other, they hoped their kids would be good friends too. Looks like that's already happening!

Jessica posted the photo at left on Instagram on July 27, showing buddies "Roc and Ace" at play. How adorable are they? They seem to be in a living room, probably in a fancy house with plenty of toys, and they're fascinated by this rug/blanket thing.

Jessica and Eric's son Ace Knute was born in late June 2013, and CaCee and Donald's son, Rocco, was born in August 2013. Hopefully they'll stay this close for many years to come.

Jessica — who now goes by Jessica Johnson — is also the proud mama of daughter Maxwell Drew, who is now 2. Jess adores her babies, but recently made it clear that she is not pushing to have Baby No. 3.

When your family is already perfect, you might as well stop there!
