Kelly Bensimon's daughter, Sea Louise, is making waves these days. We mean, can you believe The Real Housewives of New York City daughter is now 19? Yes, that's right. Kelly's little girl is all grown up. "Happy 19th Birthday to my beautiful @seabensimon," the RHONY alum shared. "You are the most incredible girl and I'm so honored to be your mamabear."

Sea Louise and Kelly are pretty close. Scrolling through Kelly's Instagram feed, it's clear that the Big Apple mom and daughter spend a lot of time together, doing all sorts of fun activities around town, along with Kelly's other daughter, Thadeus Ann.
