Sarah Jessica Parker also stopped by, wearing blue, to check out the trade show on a break from filming I Don't Know How She Does It amid reports there may be a third SATC movie in the works. Lauren has been talking up this collection, which is self-funded and close to her heart, while also showing off her latest Kohl's pieces too. LC is currently shopping around her reality show about the creation of Paper Crown after MTV passed on the project. Lauren's trip to the Big Apple comes fresh off celebrating her 25th birthday with a Las Vegas bash. LC's friend Whitney Port was also at yesterday's event with WhitneyEve and she denied rumors that the former Hills costars are fueding about The City's cancellation.
