Singer Adam Lambert will join the cast of Glee for season five, showrunner Ryan Murphy has announced.

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

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

While @AwkwardGLEE, a Twitter account devoted to the Fox musical-comedy, messaged its displeasure with a single “Ugh,” @GeriwithaG called the news “Awesome!”

“@MrRPMuphy Whoa!! That came out of left field!,” @indigo_15 tweeted. “Looking forward to seeing him on the show! :)”

While Murphy said that Lambert, 31, was joining the cast, it wasn't certain whether he meant as a guest performer or a series regular.
