The CW scored major viewer points this weekend when they announced that Doctor Who and Torchwood alum Freema Agyeman will be joining the cast of its planned pilot The Carrie Diaries, a prequel, of sorts, to the Sex & The City series.

Deadline reports that The Carrie Diaries is based on Candace Bushnell’s novel, and chronicles Carrie Bradshaw’s coming of age in the 1980s when she asks her first questions about love, sex, friendship and family while exploring the worlds of high school and Manhattan.  Agyeman will play the role of Larissa, Carrie’s mentor, a hip, cutting-edge editor/party girl who works at Interview magazine.

Many sci-fi fans will know Agyeman from her time spent on DW and TW as Martha Jones, and later in the series as Dr. Martha Jones-Smith.  Agyeman is widely considered to have been the first official companion of African descent in the history of the Doctor Who series; a fact famously disputed by Agyeman's co-star and onscreen husband Noel Clarke, who played Mickey Smith, a character who rode in the Doctor's TARDIS before Martha.

More recently, Agyeman has been seen as attorney Alesha Phillips, on ITV's Law & Order: UK.
