Michael Phelps may be the most decorated Olympian of all time, winning聽22 medals in three聽Olympic Games, but the champion swimmer just accomplished what may have been his greatest achievement of all: 聽The 30-year-old athlete and his fianc茅e, Nicole Michele Johnson (AKA Miss California USA 2010) just joined the ranks of Nick Carter, Chrissy Teigen and John Legend,聽and welcomed their first child into the world earlier this week.

Taking to Instagram to share the first-ever snaps of his newborn son, Phelps also revealed the聽strong name the couple chose for their adorable聽little boy, writing:聽鈥淲elcome Boomer Robert Phelps into the world.聽Born 5-5-2016 at 7:21 pm !!! Healthy and happy!!! Best feeling I have ever felt in my life!!! @nicole.m.johnson and Boomer both healthy!!!鈥

It鈥檚 definitely a sweet ending for Phelps and聽Johnson, who have been dating on and off since 2007, and,聽following a brief聽split in 2011, decided to give their聽love another chance. Making it official with a ring in 2015,聽the couple is now聽enjoying their first taste of parenthood before walking down the aisle (with what we can only assume will be an extra cute little聽ring bearer to boot, no less)!

New mom Nicole聽also turned to聽Instagram聽to show off her聽bundle of joy, wishing her own mama a happy Mother鈥檚 (and Grandmother鈥檚!) day, writing: 鈥淗appy Mothers & your first Grandmother鈥檚 Day to my amazing mama @annettejohnsoncoss. I love you so much mama and I can鈥檛 wait to teach my lil one all the love you taught me!!鈥 Awww!

If Phelps is chosen to wear one of the new uniforms聽as a member of the US 2016 Rio Olympic team this summer, it looks like he鈥檒l have a聽new tiny supporter rooting for him, and we can鈥檛 wait to see those photos.聽Congrats to聽the happy couple!
