The Olympic gymnast took a selfie while having a San Tropez spray tan and didn't seem to care that he was just wearing a tiny paper thong.
After sharing the snap online, Louis then went one stage further and actually filmed himself while flexing his muscles in the mirror.
He told his followers: "Just got a spray tan." The video then cuts to a clip of Louis lying down, singing: "Hey fatty boom boom, sweet sugar dumpling."
We're pleased to see Louis is opting for a fake tan rather than a sun-bed, but can't help think his footage is a little cringe?! Good body, mind!
After taking part in London 2012, Louis went on to star in Strictly Come Dancing.
