Sonya Walger

Sonya Walger has joined USA's upcoming buddy cop drama Common Law, Entertainment Weekly reports.

The Lost alum will play Dr. Emma Ryan, an intelligent and attractive Beverly Hills psychiatrist who splits her time writing pill prescriptions for her wealthy clients and offering low-cost  group therapy at the local community center. It's here that Dr. Ryan meets two homicide detectives, played by Michael Ealy and Warren Kole, who are sent into couples counseling by their captain.

USA gets hitched to Common Law

The role marks a reunion for Walger and Ealy, who worked together on the short-lived FlashForward. Walger has also starred in the HBO dramas In Treatment and Tell Me You Love Me.

Common Law starts production next month and will premiere on USA in 2012.
