Princess Beatrice reveals dramatic body transformation

Three years ago Princess Beatrice was scrutinised when an unflattering photo was published of her wearing a tight blue bikini on the beach.

The photo prompted the royal to change her diet and get into shape, fast-forward to summer 2011 and the 22-year-old now has the last laugh.

"The trouble is, I don't have much confidence so it can be quite upsetting."

"I could probably do with losing the odd pound, though, so perhaps it is the kick I need."

Last weekend Beatrice put those haunting images to rest as she was photographed enjoying a swanky getaway, with her boyfriend David Clarke aboard a luxury boat, in the South of France and showed off her toned bikini body.

Over the past two years she has dropped dress sizes from a 12-14 to 8-10 which seems to have given her the  self-assurance that she claims she lacked before.

Beatrice even brushed off the Royal Wedding hat saga that brought about a lot of criticism and embarrassment, turning it into a charitable cause by raising £81,000 at an eBay auction.

On top of exercise and diet, Beatrice has developed a strong sense of style, choosing to wear outfits that compliment her curvy frame.

Her hard work has definitely paid off. What do you think of Princess Beatrice’s slimline figure?
