EW are reporting that Grant Bowler has joined that cast of HBO’s True Blood.

Bowler most recently appeared as Wilhelmina’s lover, Connor Owens, on Ugly Betty. He is joining the cast to play  Coot, the leader of a pack of werewolf bikers.  Theo Alexander (Chuck, Pushing Daisies ) has been also been cast for the third season as Talbot, the significant other of Denis O’Hare’s, Russell Edgington.

This really has been a week full of True Blood Casting, after Shannon Lucio was cast as Bill’s wife and Marshall Allman was cast as a series regular playing Sam Merlotte’s long lost brother.

The former O.C. and Prison Break guest star has joined True Blood as Bill’s wife.

The actress will be playing Caroline, the wife that Bill never returned after becoming a vamp during the Civil War. We have briefly seen a flashback of the character during season 1, not played by Lucio.

A day full of True Blood scoop! And more to come soon, as the producers are on the lookout for an actress to play Sam’s mom and a mysterious beauty to shake things up.

Wowza.
