The Baywatch star posted this cute snap to Instagram with the caption: "I'm always asked - What inspires YOU? My answer's easy and honest...what inspires me the most is always waitin' for me to walk thru my front door when I come home."

He continued, "Happy 4 month birthday Jasmine! One day you'll know just how happy, proud, lucky and blessed you, your sister and your mama make me. You'll also thank me one day for your toughness and your mama's everything else. #HappyBirthdayJas #DaddysLilToughGirl #GratefulMan #Ohana4L."
