Team USA flag bearer and ace swimmer Michael Phelps’ son Boomer Phelps showed full support for his father at the Rio de Janeiro Olympics with posts on his social media account Wednesday.

As senior Phelps raised his career Olympic gold medal tally to 21, the infant dressed in red, white and blue with a distinct patriotic flair.

Boomer is Phelps’ son with fiancé Nicole Johnson and has been in the stands regularly as his father sweeps the swimming events at Rio. The adorable baby rose to instant fame after Phelps was snapped kissing Boomer after he won the Men’s 200m Butterfly Final during the swimming event at the Olympic Aquatics Stadium Tuesday.

The 3-month-old already has an Instagram account with an enviable number of followers. Currently at almost 250,000, the baby’s following is set to grow as the swimmer still has several events left — including the qualifiers for men’s 100-meter butterfly Thursday — giving Boomer ample opportunities to show off his cuteness.

Fiancé Johnson is not far behind with a ton of posts dedicated to Phelps on her Instagram account that boasts of over 183,000 followers. She has been routinely taking to social media to upload adorable pictures of Boomer, Phelps and his “PopPop” all sporting monogrammed “MP” merchandise by Under Armour. Johnson also showed off a Team USA-inspired special Olympic manicure in a few posts.

At Rio 2016, Phelps has already claimed three golds —  men’s 4x100m freestyle relay, men’s 4x100m freestyle relay, and men’s 200m butterfly.

If Phelps was to be considered a country with his medal tally, he would tie at 39th with Ethiopia in the all-time Olympic gold medal table. The swimmer stands two golds short of Brazil’s (the host nation) all-time tally with a number of events still left to go.
