'Pretty Little Liars' Star Tyler Blackburn Heads to 'Ravenswood' Spinoff
ABC Family's Pretty Little Liars spinoff has landed its first castmember.
Tyler Blackburn, who plays Hanna's (Ashley Benson) significant other, Caleb Rivers, is leaving Rosewood and heading to Ravenswood as a series regular. The offshoot debuts in October following Pretty Little Liars' Halloween episode.
Ravenswood centers on a town not far from Rosewood, Penn., which has suffered under a deadly curse for generations. Five strangers find themselves connected by this fatal curse and need to dig into the town's mysterious and terrible history before it's too late for all of them.
Blackburn will be seen traveling to the new town in the Halloween hour, during which Ravenswood is first introduced.
The actor -- who has been a Pretty Little Liars regular since 2011 -- still will be an integral part of the mothership's upcoming summer season before officially switching gears in October. How Blackburn's character enters into the Ravenswood equation and the future of the Caleb-Hanna relationship remain to be seen.
Marlene King, Oliver Goldstick, Joseph Dougherty and Leslie Morgenstein are executive producing Ravenswood. Alloy Entertainment and Warner Horizon Television produce Ravenswood and Pretty Little Liars.
ABC Family teased the casting announcement via social media Monday afternoon, less than 24 hours before news officially broke on all Pretty Little Liars and Ravenswood accounts Tuesday.
This is the second time the cable network has utilized social media as the first destination for key Ravenswood news. Last month, ABC Family announced the straight-to-series spinoff order and an early fifth-season renewal for Pretty Little Liars on Twitter and Facebook.
Blackburn is repped by Gersh and Lichter, Grossman, Nichols, Adler & Feldman.
Pretty Little Liars premieres season four at 8 p.m. June 11 on ABC Family.
