Glee‘s Ryan Murphy tweeted tonight that the Season 8 American Idol runner-up will join the Fox series for its upcoming fifth season. “I am thrilled to announce that the super talented Adam Lambert is joining the cast of Glee this fall,” the showrunner wrote. Murphy offered up no details about the singer’s role on the show, but this could mean Lambert’s name is off the shortlist for a seat on the Idol judges table left vacant by the recent departures of Mariah Carey, Nicki Minaj and Randy Jackson. He has been talked up as a possible replacement on the aging Fox singing competition’s panel, along with fellow Idol alums Kelly Clarkson and Jennifer Hudson. Meanwhile, this isn’t the first time network nepotism has made its way to the Glee set; 2012 Idol runner-up Jessica Sanchez made a couple of appearances this past season.
