“Pretty Little Liar” Torrey DeVitto has landed a recurring role on the hit CW series “The Vampire Diaries.” The 27-year-old starlet will play Mary, an intelligent young doctor fascinated by the self-healing powers of history teacher and vampire hunter Alaric Saltzman (Matt Davis).

DeVitto’s first two episodes are set to air when “The Vampire Diaries” returns from hiatus on Jan. 5 (this week’s episode marks its last first-run until then). According to THR, DeVitto’s character is expected to have a multi-episode arch.

DeVitto, who is married VD’s regular Paul Wesley (known to most as The Guy Who Isn’t Ian Somerhalder), currently plays Melissa Hastings on ABC Family’s teen-mystery soap “Pretty Little Liars.” Her movie creds include I’ll Always Know What You Did Last Summer and this year’s exorcism tale The Rite.

She will also be seen starring opposite Radha Mitchell and Stephen Moyer in Fourth Kind director Olatunde Osunsanmi’s Evidence, a found-footage frightener that follows police detectives as they attempt to put together a portrait of a mass murderer by utilizing his victims’ camcorders, flip cams, and smart-phones.
