Just after pics of brother, James Middleton, hit the web, Duchess Kate Middleton has one more sibling dealing with a naughty photo scandal -- sister, Pippa Middleton.

A scandalous photo of the tan and topless Pippa, 27, doing some dirty dancing with an unidentified similarly topless man, has surfaced (via Us Magazine). And although we've come to expect nothing less from the Middleton clan, it looks like Pippa sure was the life of the party -- although we have a feeling she kept things a bit more tame at sister, Kate Middleton, and Prince William's royal wedding reception.

Another photo of the stunner wearing a white mini dress and surrounded by bottles of liquor may also raise a royal eyebrow or two.
