Adam Lambert's Gleek dream comes true

UNITED STATES - Another former American Idol runner-up is heading to Glee.

Following in the footsteps of last year's runner-up Jessica Sanchez, Adam Lambert has joined the hit TV show. The fifth season of the show will air later this year.

"I am thrilled to announce that the super talented Adam Lambert is joining the cast of Glee this fall," Glee creator Ryan Murphy said.

But who the eighth season runner-up will be playing remains a secret.

To land a part in Glee is a dream come true for the 31-year-old, who once told The Hollywood Reporter that the show is "charming" and "really irresistible".
