It was just a little over three months ago that Phelps and his fiancée, Nicole Johnson, welcomed the birth of their son. The proud father made the announcement on social media.
"Born 5-5-16 at 7:21 pm!!! Healthy and happy!" Phelps posted at that time. "Best feeling I have ever felt in my life!"
The most decorated Olympian ever has since posted pictures with his son, saying "It truly is just the best... The feeling of the little guy relaxed and sound asleep on my chest!
Phelps and Johnson, a former Miss California, announced their engagement on their Twitter and Instagram accounts in February 2015. They're expected to tie the knot after the Rio Olympics,
