Adam Lambert's guest role on the Fox musical-comedy Glee is set for a November 7 debut.

Lambert's character will appear in the episode titled A Katy Or A Gaga, the first episode to air after the show returns from a three-week break.

In a clip released last week by producers, Lambert is seen performing Lady Gaga's Marry the Night. (The video is embedded on this page. Visit our video library for more videos.)

Showrunner Ryan Murphy announced Lambert's upcoming role in July.

“I am thrilled to announce that the super talented Adam Lambert is joining the cast of Glee this fall,” Ryan Murphy messaged to his nearly 500,000 Twitter followers.

“I'm so excited!! ;),” Lambert added in retweeting Murphy's tweet.
