Adam Lambert has played down speculation that he will cameo in a future episode of Glee.
Recent reports had suggested that the 'For Your Entertainment' singer had been lined up for an appearance in the hit Fox comedy.
However, writing on his Twitter account, he said: "Glee guest star rumour: it's a rumour. Sorry guys."
The former American Idol star went on to confirm reports that he would appear on The Oprah Winfrey Show and has recorded five tracks for AOL Sessions.
He added: "If I had to pick a show to guest star on I'd loooooooove to be on True Blood. Or Weeds. Those shows are amazing. Prob need some major acting classes though first. The casts of both those shows are first rate.
"I'd love to be on Gossip Girl too! Leighton is amazing. I should be Blair's shopping buddy!"
