Viola Davis, who earned her first Oscar nomination earlier this year for "Doubt," will guest star on the upcoming second season of "The United States of Tara."

Showtime announced on Thursday (June 11) that Davis will appear in seven of the 12 episodes in the Season Two of "The United States of Tara."

The premium cable network says that Davis will play Lynda B. Dozier, described as "an unconventional artist who plays a significant role in Tara (Toni Collette) and her daughter Kate’s (Brie Larson) lives."

"The United States of Tara" will resume production in August, with new episodes premiering in early 2010.

Davis, already a Tony winner for "King Hedley II," was most recently seen on the big screen in "State of Play" and "Madea Goes to Jail." Her TV credits include "Law & Order: Special Victims Unit," "Traveler" and "Century City."
