Michael Phelps' newborn baby boy is his biggest (and littlest) fan!
The Olympic swimmer's son, Boomer Phelps, sat in the stands on Tuesday, rooting his daddy on in the Olympic USA Swimming trials.
Boomer's mama (and Phelps' fiancée), Nicole Johnson, held their 7-week-old child in her arms while dad competed in the 200-meter fly—which he ended up dominating, advancing him to compete for a spot on the 2016 Olympic team in the event.
Johnson—who held the title of Miss California USA in 2010—also took to Instagram to share a precious photo of Boomer wearing a "Team Daddy" shirt. "#teamdaddy all day err day!!" she captioned the pic with the pool in the background. "We LOVE you @m_phelps00 and we're cheering super loud for you!!"
