Following the emotional tribute to late cast member Cory Monteith, Glee is taking a three week break but will then return in more celebratory fashion. On November 7, 2013 the episode "A Katy Or a Gaga" will feature Adam Lambert as a guest star. A just released promo clip shows the singer performing Lady Gaga's "Marry the Night" in flamboyant fashion. The episode is depicted as the "Katy Perrys" vs. the Lady Gagas and will land right in the midst of release of new albums by the artists.
Adam Lambert recently appeared at the iHeartRadio festival performing with legendary rock band Queen. Last year his second solo album Trespassing debuted at #1 on the album chart. The album included the top 20 adult pop hit single "Better Than I Know Myself."
