Scott Disick, 37, is “Instagram official” with new girlfriend Amelia Hamlin, 19, and the pair spent Valentine’s Day together on a beach in Miami! The Keeping Up with the Kardashians star and Lisa Rinna‘s youngest daughter were seen strolling along the gorgeous Florida shoreline on February 14 before heading to their hotel pool where they went for a swim and packed on the PDA. The father-of-three rocked a bright pink button-up shirt with matching pink Nike swim trunks and colorful sneakers.
