Pippa Middleton is back in the news and this time it's not her derriere that is in the spotlight, rather it's her breasts. The publication of the snaps shows the 27-year-old younger sister of the Duchess of Cambridge sunbathing topless. The photos, which are five years old, also show Kate in a teeny bikini and William in a red and white bathing suit. They were taken off the coast of the Mediterranean island of Ibiza.

The Middleton family has filed a formal petition to Britain's independent Press Complaints Commission. Four British tabloids have been named in the complaint which says that the publication of private holiday snaps infringed the family's privacy.
