He may have retired from professional swimming two years ago but Michael Klim still keeps his body in tiptop shape, if his wife's latest Instagram snap is anything to go by.
Currently holidaying in Croatia, the sportsman's partner Lindy has been sharing their adventures through social media, including a visit to a local nudist beach at the weekend.
The former model and Balinese princess posted an image of a naked Klim standing by a sign with the words "nudists welcome", his muscular back and tattoos clearly visible in the shot.
Lindy joked her husband of eight years had "finally found his people".
And not to be outdone, she later uploaded a second snap that showed her in a revealing white bikini on her way to a Croatian bathhouse.
The famous pair, who divide their time between bases in Melbourne and Bali, wed in 2006 and have three children together - Stella, 7, Rocco, 5, and Frankie, 2.
Retired swimmer Klim is now an elite-school swimming coach and has brought out a line of lifestyle products.
