LONDON:

Kate Middleton flaunted her trim figure in a black and white bikini while holidaying with

her boyfriend Prince William in the Caribbean island of Mustique.

The 26-year-old brunette was photographed wearing the bikini while relaxing with William on a boat. Kate even tried wakeboarding and was towed in an inflatable ring alongside William, reports thesun.co.uk. The couple have been staying at a five million pound villa in Mustique after the 26-year-old British prince ended his month-long stint on a naval warship. A royal insider said, “It’s the first time they have been seen on summer holiday for two-and-a-half years. It will intensify suggestions of an engagement.”
