Olympic legend Michael Phelps and his wife Nicole shared some happy news on Sunday. They’re set to be parents for the third time as Nicole is expecting another kiddo.

Both Michael and Nicole Phelps (who wrote “Oops, we did it again“) shared their news on Instagram with the cutest picture of their two sons, Boomer and Beckett.

It’s clear that the Phelps family either doesn’t know or isn’t telling whether No. 3 is going to be a boy or a girl.

Wishing them all much joy as they prepare for the new addition!
