UFC boss Dana White just delivered some of the rawest life advice we've heard from a celebrity in a long time - and he did it on a random sidewalk, no publicists in sight. White was walking down the street when he ran into Peter Fouad, a street photographer with 1.7 million followers on TikTok who's built a massive audience with a dead-simple concept. Fouad catches celebrities off guard, asks them one question - what's the best life advice you've ever received? - snaps a Polaroid on his Fujifilm camera, and lets them keep the print.
