The potential series is an hour-long scripted E! drama written by ex-Grey’s Anatomy scribe Krista Vernoff and executive-produced by Smash duo Craig Zadan and Neil Meron. It centers on Lauren, a genius songwriter who employs a small staff — including Mickey — to manage her strange-yet-successful process.

Willis’ character, who began working for Lauren after an “episode” forced her to drop out of law school , is secretly pursuing her own singing and songwriting ambitions.

The actress recurred on 90210 as Gia, Adrianna’s ex-ladylove; her other recent TV credits include Pretty Little Liars, Hawaii Five-0 and Workaholics.
