Michael Phelps' gold-winning dad moments with Boomer

Michael Phelps may be an Olympic champion, but as it turns out, the athlete's all-star skills extend well beyond the swimming pool. Since welcoming his son Boomer Phelps with fiancée Nicole Johnson in May 2016, the legendary swimmer has proven to be a gold-winning dad.
Check out the father-son duo's cutest moments together.
