Someone better make room on the crowded Twilight bandwagon, ’cause Criminal Minds is jumping on.

The CBS procedural has tapped Jackson Rathbone — a.k.a. Twilight vamp Jasper Hale — to guest star in an upcoming episode directed by Seinfeld‘s Jason Alexander.

Rathbone will play a college student on spring break who may or may not be the target of a serial killer.

His episode is slated to air in April.
