Ace Knute is super cute!
Jessica Simpson's son with fiance Eric Johnson turned 3 months old on Saturday -- and the 33-year-old celebrated by sharing two new photos of their big boy.
He definitely knows how to strike a pose!
Simpson looks prettier than ever in the shots too, looking like a proud mama with a fresh, makeup-free face.
The mother-of-two recently showed off her post-baby bod on Eric's birthday, putting her cleavage on display in an all-black ensemble.
And while she's been busy with her kids and life at home, it sounds like she may be going back to the recording studio soon.
