The swimmer, 32, celebrated the upcoming arrival of the couple’s second child with a baby shower on Sunday. He shared a photo holding 21-month-old son Boomer Robert and standing next to Nicole, whose growing belly was on display in a fitted green dress and sleeveless beige cover-up.
“Thanks to those who came to celebrate today!!” Phelps captioned the family photo, adding the hashtag #babyshark, which guests used to share their snaps. (Perhaps it’s a reference to the 28-time Olympic medalist racing a shark as part of Discovery Channel Shark Week?)
Nicole, also 32, posted a sweet shot of her husband with his hand on her bump. “Such an amazing day celebrating our #babyshark!!” she wrote. “More photos to come … we are so thankful for everyone who was able to be with us and everyone who was with us in spirit.”
