John Mulaney shared the cutest now vs. then shots of himself and his son Malcolm 🥰 The comedian and father of two, 43, was feeling nostalgic and so happy to be back at the Red Rocks Amphitheatre in Colorado with his son, 4, looking so grown up since their last visit when he was just four months old. The father-son duo rocked matching jackets as they stood on stage getting ready for John's show, looking like the sweetest pair ✨ 📸 : #JohnMulaney #nowvsthen
