Jesse McCartney Is Going Greek

Singer Jesse McCartney (“Summerland”) has joined the cast of ABC Family’s “Greek” the network revealed in a press release today.

McCartney will play Andy, a high school friend of Calvin’s (Paul James), who also happens to be a highly sought after pledge.

“Greek” will return with all new episodes in Spring 2009 as Casey (Spencer Grammer) enters her senior year at Cyprus-Rhodes University and is faced with secret sorority and spies while Rusty (Jacob Zachar) returns as a sophomore and an active Kappa Tau member.

Meanwhile, the fraternities and sororities are bracing for an exciting rush week with new incoming students — let the battles begin! Ken Marino (“Veronica Mars,” “Reaper”) is also set to guest star in the mid-season premiere as a fellow summer camp counselor with Rusty, played by Jacob Zachar.
