Royal wedding guests
Thomas van Straubenzee, seen here with Kate Middleton at a rugby match on Feb. 10, 2007, in London, is one of Prince William's closest friends and is expected to be in attendance. Known as "Van," he met the prince as classmates at Ludgrove Prep School. They frequently travel together, including the time when William toured New Zealand in 2005.
