While all eyes this week will be on Britain's Prince William -- who turns 18 on Wednesday -- some attention is also being focused on the increasingly public relationship of Prince Charles and his longtime love, Camilla Parker Bowles. Two weeks after Queen Elizabeth met and spoke to Parker Bowles at a social function at Charles's estate, the Prince and Parker Bowles are expected to attend an official royal dinner tomorrow night, reports Britain's Press Association. Those on the guest list include Virgin chief Richard Branson and designer Donatella Versace. A spokesman for the Prince confirmed that Charles is hosting the dinner, to be held at the new headquarters of the Prince's Foundation charity, but he refused to say whether or not Parker Bowles would attend.
