Females on a stag night? Charles to have a 'Hag' night dinner!

Prince William and his sweetheart Kate Middleton, have been invited on a ski holiday with Prince Charles for his stag 'week', Prince Harry and around 30 of the royal friends are attending, a leading tabloid reported today.

Kate's presence yesterday in Klosters - her second visit with the family to the Swiss resort - shows how serious 22-year-old William is about her, The Mirror claimed. It also indicates she has the royal seal of approval.

At one stage the 21-year-old pretty student stifled a giggle as she sat next to Charles at a restaurant table, the report said.

Kate, who shares a cottage with William at St Andrews University in Fife in Scotland, also joked with Harry, 21, as the group headed for their first day on the slopes. Kate is daughter of Company Director Michael Middleton. Others on the trip include Tara Palmer-Tomkinson, her dad Charles, sister Santa and Santa's author husband Simon Sebag-Monterfiore.

Harry's mate Guy Pelly, once wrongly accused of introducing him to cannabis, is also there. And the group made a royal ascent up the slopes yesterday in a ski-lift called the Prince of Wales, its name emblazoned on the side.

The sag 'week' will also feature a stag night dinner to mark Charles's April 8 wedding to Camilla Parker Bowles.
