After picking up his 20th and 21st gold medals in the pool in Rio on Tuesday, nobody could steal the spotlight from U.S. Olympian Michael Phelps.
Nobody, that is, except the swimmer's 3-month-old son Boomer.
Boomer has been in the crowd at the Olympics cheering on his record-breaking dad - and stealing a bit of his thunder while he's at it. Not that Michael Phelps seems to mind. After taking the top spot in the 200-meter butterfly, he ran over to the stands to give a celebratory kiss to his son, as well as to his fiancee Nicole Johnson and his mom Debbie Phelps.
Take a look at Boomer's adorable Olympic debut:
