William, Kate celebrate New Year's Eve in a teepee

(CBS) It was a family affair for the British royals on New Year's Eve. Prince William and his wife, Kate, Duchess of Cambridge, rang in 2012 at an event thrown by Kate's party planner sister, Pippa Middleton.

According to the U.K.'s Daily Mail, Kate and William celebrated their first New Year's Eve as a married couple at a bash held at the Middleton family home in Berkshire, England.

They celebrated the start of 2012 in a tent, a lavish teepee-style kata made of animal hides typically used for cooking, smoking fish and as a shelter from heavy snow.

The space featured a dance floor and seating for about 100 guests. William's brother, Prince Harry, didn't attend; he reportedly spent New Year's Eve at the Swiss ski resort of Verbier.
