Pippa Middleton is to be forgiven her recent fashion faux pas at a friend's wedding. Friday night, the royal sister sizzled on the scene of a charity event in a daringly low-cut gown.

Pippa dazzled in the red full length dress, designed to take the eye right to her cleavage!

The lucky man escorting Kate Middleton's sis was her boyfriend Alex Loudon. The pair attended a boxing event that benefited the Starlight Children's Foundation, an organization that grants wishes to kids suffering from life threatening illnesses.

Former Spice Girl Geri Halliwell chatted up Pippa during the evening. Also there were the ever-present princesses Eugenie and Beatrice, cousins to Pippa's brother-in-law, Prince William.
