EXCLUSIVE: Former 90210 showrunner Rebecca Sinclair is back at the CW with a new hourlong dramas. It is one of two projects she has set up at CBS TV Studios, the studio behind 90210. She will write and executive produce both.

The untitled CW drama centers on a self-obsessed young pop star – the black sheep of her religious family – who isn’t interested in saving anything but her own career, until a fan claims to have been miraculously healed by her touch and word spreads that she has divine powers.

The second project, The Lost Girls, is being developed internally at CBS Studios with Ridley Scott’s Scott Free. It is based on travel memoir The Lost Girls by Jennifer Baggett, Holly Corbett and Amanda Pressner. The TV project, which adds a mystery element to the story in the book, centers on four very different 20-something American women, each at a point of crisis, who decide to escape their lives and their country, and go abroad.  While in Cambodia, the wanderers bond, happy to find friends who are equally lost. But when one of the women vanishes under mysterious circumstances and the remaining three pledge to find her, they embark on the real journey, a quest that leads them off the beaten path, around the globe and on the road to finding themselves.

In 2006, friends Baggett, Corbett and Pressner, who had been climbing the corporate ladder of Manhattan media, left their jobs, boyfriends, apartments and everything familiar behind to embark on a year-long search for adventure and inspiration. They chronicled their journeying across four continents and more than a dozen countries on their website, LostGirlsWorld.com, and later turned that into a travel memoir published by HarperCollins in 2010. That same year, ABC gave a put pilot commitment to an hourlong adaptation of the book and the blog, which was produced by Jerry Bruckheimer TV and Warner Bros. TV and written by Ildy Modrovich.

Sinclair served as executive producer/showrunner on 90210 for three seasons. She took the reins of the show toward the end of its rocky first season and is credited with turning it around. Sinclair, repped by UTA and Hansen Jacobson, left in spring 2011 to focus on development. She previously served as co-executive producer on Gilmore Girls.
