Pippa Middleton Does Bikini Back-Flips Off Of Will & Kate's Yacht! (PHOTOS)

New photos of Kate Middleton and Prince William from before the Royal Wedding have surfaced and show the couple enjoying each other's company with Kate's sister Pippa and the rest of her family, long before any royal duties or familial obligations were on their minds.

Kate, looking fantastic in a white bikini, brought Prince William along with her sister Pippa, their mother Carole and their brother James on a boat belonging to Carole's brother Gary Goldsmith during a week-long sunshine holiday to Ibiza. 

Pippa played around and did graceful backflips off the back of the boat, while Kate stood back and watched. William tried his hand at a few dives as well. 

The photos were snapped back in 2006 and show the genetically gifted clan horsing around and doing backflips off the boat. Check out more photos on the next pages.
