Jessica Simpson posted photos to Instagram late Sunday night proving her children’s Easter weekend was filled with sweet memories in the making.
First up, Simpson, 33, shared a scrumptious shot of son Ace, 9 months, curiously examining the ear of a beaming Rocco, the 8-month-old son of BFF CaCee Cobb and husband Donald Faison, during a joint bath.
“Bunny babies,” Simpson captioned the aww-inducing photo of the next generation BFFs.
“BX and Maxi have the same shy face. Cousins!!” she captioned the shot.
Something else they have in common? Impressive egg-finding skills: both have baskets chock full of colorful eggs. Considering the two kids are holding hands, it looks like they found them in harmony.
