Jessica Simpson makes sure hubby Eric Johnson remembers just how charmed his life is.

The onetime pop star and current billionaire celebrated Father's Day with an adorable Instagram post featuring their two kids, Maxwell, 4, and Ace, 2, who are looking all grown up and more alike than ever!

"Dear Daddy Eric, Thank You. Love, Maxwell Drew and Ace Knute Johnson," Simpson captioned the shot, before adding, "Mommy might Love you way too much. #HAPPYFATHERSDAY"

The 35-year-old mother slash mogul shared another sweet photo of the kiddies poolside, writing, "14 months apart and my blondies are trying to figure out which one will share or get thrown in."

And lest you forget that Simpson is also obsessed with Johnson -- which, how could you? -- she shared an, ummmmmmm, interesting picture of her husband half naked and covered in paint.

"Maxwell made Daddy her canvas. 'Dad you be half tiger half dragon ok?' I love my husband," she sort of explained. Why not!

Meanwhile, in other Father's Day news, Kelly Clarkson posted the cutest pic of her newborn son and thanked her "sexy" husband for being such a "great dad." Check it out in the video below.
