'American Idol' host Ryan Seacrest has reportedly approached Sarah Jessica Parker about launching a fashion-based reality TV show together.

Seacrest, who worked with Parker while filming the romantic comedy 'New Year's Eve', is allegedly hoping she will agree to host the series.

An insider told Bang Showbiz: "He thinks she's the perfect fit for the show. He adores Sarah and is determined to let her know they'd be perfect for the project."

The 'Sex and the City' star previously made a guest appearance on 'Project Runway' in 2007, and is said to be keen on the idea of being involved with a fashion show.

The source added: "Sarah has talked about doing a TV show revolving around the fashion world for years. It's a natural fit."
