You has found its Joe.

Penn Badgley, best known as Gossip Girl‘s Dan, will star in the forthcoming Lifetime drama from Greg Berlanti (The Flash and about 300 other series) and Sera Gamble (Magicians), TVLine has learned.

The psychological thriller is based on Caroline Kepnes’ 2015 novel, in which Joe, a bookstore owner, uses social media and technology to feed his obsession with an aspiring writer. (The part of the writer has not yet been cast.)

Badgley’s other TV credits include The Slap, The Young and the Restless and Will & Grace.

You received a straight-to-series order from the basic cabler earlier this year.
