"Sex and the City" author Candace Bushnell is in talks to turn her new book "Lipstick Jungle," the story of three successful career women in New York, into a television series.

"I haven't signed any deals yet but there's a lot of interest," Bushnell told Reuters. "Nothing's been finalized but hopefully it will be in the next couple of weeks."

In an interview ahead of the September 6 publication of her latest novel, Bushnell said it was too early to discuss who might play the three main characters -- a film producer, a fashion designer and a magazine executive.

HBO's Emmy-winning "Sex and the City," the TV series about the love lives of four single women in New York, ended in 2004 but reruns still feature heavily on U.S. cable stations.

Bushnell said "Lipstick Jungle" was a "pretty philosophical kind of book" about what happens when women like the thirty-something women of "Sex and the City" get into their forties and experience real success in their careers.

"I see it more as a TV show than a movie," Bushnell said. "One of the things that's really hard with movies these days is that it's almost impossible to have forty-something women."

"There are probably three parts a year for a women of over 40 and happily on TV there are many more opportunities," said the author, who is 46 and who originally wrote "Sex and the City" as a newspaper column in 1994.

"There's a lot of interest in 'Lipstick Jungle' becoming a TV series but it's just a little bit too soon, in a couple of weeks I could tell you all about it," she added.
