Sarah Jessica Parker & Greg Kinnear Read a "Leaked" Script From 'Sex and the City 3'

Sarah Jessica Parker may not know if a Sex and the City 3 will ever hit theaters, but MTV's Josh Horowitz got his hands on a "leaked" script for the film and asked SJP and her co-star Greg Kinnear to act it out!

While SJP and Greg were promoting their new film, I Don't Know How She Does It, Josh asked the SATC star to discuss the potential third film.

“We don’t know,” Sarah said with laugh to MTV. “But if you do, please do let me know!”

So instead, Josh pulled out a "top secret" page from the script and had had SJP and Greg read parts for his web series, "Leakage."

Sarah was playing Carrie, Greg playing a man named Rex and Josh was reading for Samantha — naturally.

Apparently, Josh's script has the ladies caught in a "time vortex" — much like Back to the Future Part III.

"It was a very important film in my childhood," Josh explained.
