Stephen Colbert takes over the reins of CBS’ The Late Show on 9/8. As Variety reports, Colbert revealed today that Kendrick Lamar will be his first musical guest — which is fitting, as Kendrick was the last musical guest on The Colbert Report, where he performed an incredible untitled song that he apparently wrote the day before the show. George Clooney is also set to appear on Colbert’s first Late Show, so it should be a fun time.
