Jessica Simpson isn't quite ready for her daughter, Maxwell, to turn another year older.

The 35-year-old mother-of-two posted a sweet pic of her little girl, just days before her fourth birthday. "This beauty is at the end of her 3's," Simpson wrote, along with the hashtags #HOLDYOURHORSESMAY1 and #MAXIDREW.

While Eric Johnson's wife is bracing herself for when she has a 4-year-old in the house, Simpson told ET in September that she doesn't want any more babies. "No more kids on the horizon," she admitted. "That would freak me out a little bit."
