Nicole Johnson, the fiancee of Olympic champion Michael Phelps, is pregnant. Phelps announced the exciting news via social media on Wednesday.

“We found out eight weeks ago that we were expecting,” he captioned his Instagram post. “Today we’re over 12 weeks and it looks like we’re having a boy! #babymp #lifeabouttochange #mpswim @djnolan5”

It was last February when Michael Phelps proposed to Nicole Johnson. The 22-time medalist shared that news via Instagram, too. Prior to becoming engaged, Nicole Johnson and Michael Phelps dated on and off for several years.

Michael Phelps has been plagued with two DUI arrests in recent years. He has been to rehab and still works hard to maintain his sobriety.

“Haven’t had a single sip and will not have a sip,” he said earlier this month. “I worked, recovered, slept, and took care of myself more than I ever had.”
