Boomer Phelps is getting a brother or sister.

The Baltimore Bullet and his wife, Nicole Phelps, announced via Instagram this afternoon that theyโ€™re expecting a second child.

The couple married in 2016 โ€“ three times, for full transparency โ€“ and had baby son Boomer one month before their secret initial wedding ceremony in June. He may have been a good luck charm: three months after he arrived, his dad kicked off a monster Olympic run that earned him five more gold medals and a silver, bringing his career count to to a record total of 28.

Boomer is now coming up on 16 months. The odds are strong that heโ€™ll be a great swimmer โ€“ heโ€™s already seen some time in the pool with his Olympian dad.

Phelps should have plenty of time to devote to fatherhood now that heโ€™s retired from the sport that made him famous. Heโ€™s stayed busy after stepping away from swimming, scoring endorsements, racing a fake great white shark on TV and exploring Silicon Valley. But barring a comeback, heโ€™ll in the clear to enjoy an early retirement with his growing family.
