Pipin’ hot PIPPA MIDDLETONhas shimmied her way into the Royal Family and has now been invited to their much maligned Boxing Day Pheasant Shoot.

As well as party planning, being a socialite, and having her rear end the subject of much discussion, Pippa is also apparently a rather good shot and is excited to be part of the day-after-Christmas festivities.

The 28-year-old younger sister of the Duchess of Cambridge will join the Queen and the rest of the senior royals in an unusual move – immediate Royal Family members only .

But since this  will be sister Kate Middleton’s first Christmas with her husband at Sandringham,  Pippa's invite may have been to help her sis feel comfortable and at ease away from her parents for the holidays.

“Pippa’s very keen to go and she’s been on a couple of shooting weekends to make sure she won’t let the side down,” a source told the Daily Mail.
