Michael Phelps put on one memorable show at the Rio Olympics and is now safely back in Arizona.
Phelps posted a precious photo to Instagram with fiancée Nicole Johnson and 3-month-old baby boy Boomer in the pool as he kicked off his retirement.
“There’s nothing like being back home!! Great way to spend my first day in retirement!!” Phelps wrote on Instagram.
How cute is Boomer?!
