Simpson posted new photos Wednesday of the family's part for the NFL player's 33rd birthday on Saturday, Sept. 15.

"Last year at Daddy's party, Maxwell was in my belly," the proud new mom wrote. "This year she's in my arms!"

Simpson, 32, shared an adorable photo of herself smiling for the camera while holding Maxwell, 4 months. In honor of her dad's birthday, baby Maxwell was wearing a tiny bow on her head.

Simpson and Johnson have been focusing on their bundle of joy and haven't made plans for their wedding yet. But the Fashion Star judge told iVillage, "I know it's going to be a perfect wedding, and . . . I mean, I say that, and it could not be . . . we really haven't planned it," she confesses. "But I see it being definitely a destination thing and everyone celebrating and being able to dress up and having all of my bridesmaids looking beautiful in whatever designer they want to wear."
