Michael Phelps and Nicole Johnson wed on Saturday in Cabo San Lucas, Mexico after secretly tying the knot all the way back in June.
The couple invited approximately 50 of their closest family members and friends to the intimate occasion, including a full bridal party and their 5-month-old son, Boomer.
The 23-time Olympic gold medallist shared an Instagram photo Sunday of him walking down the aisle with the former Miss California USA, captioned, "My best friend.... I love you!!" Johnson also shared a picture of her walking with Phelps on a beach while dressed in a wedding gown.
Nicole acknowledged the wedding day bliss as well by changing her Instagram moniker to 'mrs.nicolephelps' and adding a different photo with the caption, "Truly the happiest day of my life @m_phelps00 thank you @boonestudios for capturing this day."
