Guys' night out!
But not just any fellas, mind you.
The swimmer joined fellow Olympic pool boys Michael Phelps and Conor Dwyer at a party hosted by Details magazine as part of New York's Mercedes-Benz Fashion Week.
Trading in their Speedos for dapper duds worthy of, well, fashion week, the trio was all smiles as they happily posed for pics.
Talk about a reunion worthy of a gold medal!
