Vocal powerhouse Adam Lambert has opened up about shooting the upcoming 'Glee' episode called 'Frenemies' and confessed that it was particularly exciting because not only were they singing a rock song, but the set featured a stripper pole. 

Talking to the camera about the episode, Lambert explains: "This episode, I think it's just exploring the relationship of all the characters that are friends and hang out with each other, but are having some drama."

The pair perform a rendition of 'I Believe In A Thing Called Love' by The Darkness and show off their moves on stage although cast member Chris Colfer walks over to a pole and dances around it, which impressed Lambert. Colfer admitted: "Adam was kind of like, 'the stripper pole's all you... you have fun with that', and I did!"

The 'Trespassing' sensation then joked that Colfer was pretty good at working the pole, adding: "Chris is kind of inclined for the stripper pole! I'm impressed... he's got some moves!"
