British royal PRINCE ANDREW is reportedly dating American actress Angie Everhart, who he took to his daughter BEATRICE's 18th birthday party on Saturday (15JUL06). Andrew surprised guests at the lavish Windsor Castle bash in England when he arrived with the LAST ACTION HERO star. An insider tells British newspaper The Sun, "Prince Andrew is besotted with Miss Everhart. They have become very close in the past nine months in particular. "But until she turned up on Saturday, no one knew just how close they had become."
