In August, the couple announced in matching social media posts that they are expecting again.
Phelps and the former Miss California USA welcomed Boomer in May 2016. They wed later that year – twice! First, the pair tied the knot in June, and then again in late October during a larger event in Cabo San Lucas, Mexico.
Phelps previously revealed to PEOPLE that his wife was looking forward to growing their family, sharing, “Nicole has recently brought up that she would like a girl!”
“We definitely want more kids, it just depends on when. I’m sure I’m getting pressure” he said, teasing, “[We’re] trying to get moving on some things!”
Adding, “We’re going through life every day happy and blessed with what we have. But I hope to have more kids in the future.”
