'True Blood' season five adds child actor Jacob Hopkins

Jacob Hopkins has won a recurring role on True Blood.

The child actor will play Alexander Drew, a member of the Vampire Authority, according to The Hollywood Reporter.

Transformed into a vampire at age 9, the impulsive, unpredictable Drew likes to taunt those around him.

Hopkins has previously appeared in episodes of How I Met Your Mother and played a small role in the 2011 film Priest, which also featured True Blood's Stephen Moyer.

Other stars to have signed up for roles on True Blood include Law & Order: SVU's Christopher Meloni and Spartacus actor Peter Mensah.

The HBO drama's fifth season is currently in production and will premiere this summer.
