We weren’t the only ones worried about our additional holiday pounds—Kate Moss is worried about her figure after over-indulging in Thailand.

The supermodel, who is currently in the Asian country on an extended New Year break, has been tucking into plates of fried food and is now starting to regret her actions after piling on some pounds.

A friend of the 35-year-old beauty said, “Kate’s been a bit naughty on holiday. She decided to spoil herself, so she’s been ordering egg and chips a hell of a lot. Now she’s staring to regret it. She’s having to leave the top button of her jeans undone in the evening and is worried she’s put on timber.”

Although she has been over-indulging with the food, Kate has been exercising on her break as she recently learned a synchronized swimming routine.

A source said, “Kate has spent five days solid preparing for this synchronized swimming display. Underwater music was piped through her hotel pool, allowing her to practice her moves and refine the art of water ballet.” The catwalk queen is taking the swimming so seriously that she has been studying from a guide book to help her perfect her moves.
