On the eve of Stephen Colbert‘s final show on CBS, the host invited Bruce Springsteen to the stage for a performance of his protest song, 'Streets of Minneapolis.' Springsteen made it clear why he was there for the late-night series penultimate episode. “I’m here in support tonight of Stephen, because you’re the first guy in America who lost his show because we’ve got a president who can’t take a joke.” Also: 'Riverdale' star KJ Apa is "excited and a little nerve-wracked" to see his Jimmy Stewart biopic, which just released a new trailer! The actor stars as Stewart in 'Jimmy' which traces the life and career of the Hollywood icon beloved for films like 'Vertigo.'
