Prince William and girlfriend Kate Middleton have finally found the time to spend quality time together.

The royalty and his special girl recently spent time in the Caribbean aboard a speedboat. Some friends were also with them.

The pair has been together for six years.

Middleton, 26, waterskiied and relaxed in a black and white bikini. Prince William, also 26, wore blue board shorts.

"They only planned on a week there, which is a bit unusual, as they still have some time together before he continues military training," a royal insider has told PEOPLE.
