Pippa Middleton offered $5 million to do porn

Pippa Middleton has been offered $5 million (£3.05 million) by Vivid Entertainment to appear in a porn film.

According to TMZ, the sister of the newly married Kate Middleton was sent a letter by Vivid co-chairman Steven Hirsch after she impressed at the royal wedding wearing a Sarah Burton-designed dress and has been tipped to win this year's 'Rear of the Year' title.

Hirsch said that she would be able to freely choose her sexual partner and would only be required for one "explicit" scene.

The letter read: "As far as I was concerned, you were the star of the recent royal wedding.

"As I watched a broadcast of the event, I couldn't help but think that with your beauty and attitude, you could be an enormously successful adult star. This week, after seeing photos of you having a great time at a party, I decided to offer you a role in one of our upcoming movies."

Hirsch also tabled an offer to Pippa's brother James to feature in a separate scene for $1 million (£611,000).

Vivid Entertainment was previously interested in distributing a sex tape featuring Heidi Montag and Spencer Pratt, though Montag was said to be strongly against the idea.
