Kate Moss has taken up synchronised swimming.

The British catwalk beauty spent almost a week mastering a water dance routine at a luxurious hotel in Phuket, Thailand - where she saw in the New Year - before performing for a big group of friends, including fellow model Naomi Campbell yesterday (05.01.10).

A source said: "Kate has spent five days solid preparing for this synchronised swimming display."

The 35-year-old style icon took the task so seriously she even wore professional attire and studied from a guide book to help her perfect the challenging moves.

The source added: "Underwater music was piped through her hotel pool, allowing her to practise her moves and refine the art of water ballet. Sporting a nose clip and floral swimming cap - worn ironically - she had a hotel worker download an online handbook so she could learn all the moves.

"Kate has perfected all the basic sculling moves and twirls, plus the eggbeater - basically treading water - but has really struggled with the crane which requires a great deal of core strength."

Kate's week of training ended last night (06.01.10) with an alcohol-fuelled performance which left her friends and rocker boyfriend Jamie Hince in hysterics.

The source told the Daily Mirror newspaper: "Last night she invited a group of model friends, including Naomi, to her villa for the show. It was a roaring success and everyone was in hysterics watching Kate and co. pirouetting underwater.

"The only blip in the evening was when a rather tipsy Kate tried to jump back in the pool at midnight for an impromptu solo performance. Boyfriend Jamie Hince had to physically hold her back. But Kate reckons it's been amazing for her bum and tum, and has really toned her up."
