US swimmers rock out in carpool karaoke

Rio de Janeiro - The carpool karaoke craze has come to the Olympics courtesy of the US swimming team.

Michael Phelps, Katie Ledecky, Missy Franklin and Co. let themselves go at a Stateside pre-Games training camp in their version of the TV sketch in which celebrities rock out in the car.

They unleashed an eight-minute video montage on YouTube on Thursday that features more than 40 swimmers and nine different cars.

Freestyler Simone Manuel shines in her interpretation of One Direction's What Makes You Beautiful, while medley swimmer Maya DiRado shows off some solid seat-dancing moves to Fifth Harmony's Bo$$.

Phelps and Allison Schmitt contribute a soulful version of Zac Brown Band's "Chicken Fried" while Ryan Lochte presides over a riotous trip through a fast-food drive-through.

Add in the Pokemon theme song, Miley Cyrus's "Party in the USA" and a couple of random lobster costumes and it looks like the Americans are plenty relaxed heading into the Rio swimming competition that starts on Saturday.
