Michael Phelps shared his first retirement photo with fans on Instagram earlier this week.

After arriving home from Rio, the U.S. swimmer enjoyed some family time with his soon-to-be wife, Nicole Johnson, who he plans to marry later this year, and their son, Boomer Phelps.

"There's nothing like being back home!! Great way to spend my first day in retirement!! @boomerrphelps @nicole.m.johnson," Phelps captioned the photo below.

Days before sharing his latest photo, Phelps confirmed his retirement during an interview on the Today show and revealed how he would be spending his retirement.

“Done, done, done — and this time I mean it,” Phelps told Matt Lauer, according to a report by Gossip Cop on Monday. “I wanted to come back and finish my career how I wanted, and this was the cherry on top of the cake that I wanted.”

Although Phelps opted to come out of retirement after intially announcing plans to leave his swimming career behind after the 2012 Olympic Games in London, Phelps told Lauer that this time around was much different.

 “The biggest thing between now and London, I was so much more emotional during these games. I think that showed at times on camera. That’s the difference, because I knew this was the last time. I knew this was the last race that I ever had, the last Olympics that I ever had. And everything just really hit hard,” he explained.

Continuing on, Phelps said he was looking forward to “build[ing] a family” with Johnson.

“This is the part of my life where I get to start this whole new chapter,” Phelps said.
