Michael Phelps, the most decorated Olympian in history with 28 medals, and his wife Nicole are expecting their second child.

This will be the second child for the Phelps family. Boomer Robert Phelps was born May 5, 2016, just in time for Phelps’ last Olympic hoorah.

Phelps retired from swimming for a second time after the winning five gold medals and one silver medal at the Olympic Games Rio 2016. Earlier this year, he staged a swimming competition against a graphically-generated shark. He previously retired following the 2012 Olympics.

Phelps holds records for the most Olympic medals (28) and most Olympic gold medals (23). He won eight gold medals at the 2008 Beijing Games to break the single-Olympic record of seven set by fellow U.S. swimmer Mark Spitz in 1972.  

A five-time Olympian, Phelps competed at his first Olympics, the 2000 Sydney Games, when he was 15 years old, the youngest man to make a U.S. Olympic swimming team since 1932.
