Sarah Jessica Parker 'turns down prequel TV offer'

Sarah Jessica Parker has reportedly turned down $500,000 to appear in The Carrie Diaries.

The actress portrayed Carrie Bradshaw in the TV show Sex and the City and the two subsequent movies.

AnnaSophia Robb is now playing a younger version of the character in The Carrie Diaries, which is a prequel to the hugely successful series. It has been reported that although Sarah was asked to appear in a flash-forward sequence, she decided against it.

"Sarah doesn't need the money and wasn't sure appearing on the show would be the right career move," an insider told National Enquirer. "It would be like taking a step backward. So she's said goodbye to Carrie forever. Plus, who wants to be compared to a teenager?"

The Carrie Diaries has already hit screens in America and AnnaSophie admits she felt nervous when the day dawned.

She was even concerned about what Sarah Jessica would make of the show, which made a move by the older actress even sweeter for the young star.

“[Sarah Jessica Parker] sent me a very lovely note just kind of giving me her blessing and encouraging me and telling me how excited she was and how dear the part was to her, and so that was huge for me because, you know, I was obviously nervous,” AnnaSophia recently explained. “I was, like, ‘Is this OK?’ And so it just meant a lot to be able to have her blessing.”
