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.
Two hours later, Simpson posted a sweet photo
of daughter Maxwell
, who turns 2 May 1, cozying up to cousin Bronx
, the 5-year-old son of engaged
sister Ashlee Simpson
, during an egg hunt.
"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.
