Michael and Nicole were married in a secret wedding in June 2016, a month after Boomer was born. The couple had a public wedding in October 2016, followed up with a party to celebrate their nuptials with family and friends on New Year’s Eve 2016.

Photos were widely shared in the news and on social media as Nicole and infant Boomer cheered on Michael from the stands during the 2016 Olympic Games in Rio. At that time, Phelps won a gold medal in the final race of his career by swimming the butterfly in the 4×100-meter medley relay.

Nicole, 32, is a model who was Miss California 2010 and competed in the Miss USA pageant. She was born in Colorado, grew up in Pennsylvania, and then moved to California, where she went on to compete in multiple beauty queen pageants. She is an alumnus of the University of Southern California, having graduated with honors in 2007.
