Michael and Nicole Phelps are about to become parents...again! The Olympic swimmer and his wife are expecting their second child.

Both Michael and Nicole shared the exciting news on Instagram, where they posted matching pregnancy announcements.

"Number 2 on the way!!!! So excited!! Wonder if it's a boy or a girl??" The Olympian wrote alongside a sweet photo of his wife posing with the couple's son, Boomer.

Boomer—who is already something of a social media star at just 15 months old—also 'shared' the big news in his own Instagram post. Boomer's "people" added a photo of the adorable toddler clapping gleefully while standing behind his mom's positive pregnancy test. "So excited to see what mama is having!! Do I get to have a brother or a sister?!?" the photo's caption reads.

The soon-to-be-father-of-two is anything but a fish out of water when it comes to parenting. "The last year has gone by so fast," he previously told "But we are enjoying the ride and it's only gonna get better."

And with a second baby in the mix, it'll be double the joy!
