Michael Phelps, who scratched out of the Atlanta Classic Swim Meet next week, just announced the birth of his baby boy Boomer Robert Phelps with fiancee Nicole Johnson.

The couple welcomed their child two days ago on May 5 at 7:21 p.m., but withheld the announcement of the birth until after Michael’s sister Hilary Phelps’ wedding took place today

Phelps, who had just been in Colorado Springs at the Olympic Training Center (as seen in this Facebook Live video tour of the facility), rushed back to Arizona on Thursday to be with Nicole.

There has never been an Olympian with the first or last name of "Boomer," according to the experts at sports-reference.
