On The Late Show With Stephen Colbert, he's known for his congenial interviews, quick-fire banter, and polished professionalism. But sometimes even Stephen Colbert gets a little star-struck. (Talk show hosts—they're just like us!) Whether he's mugging with S.W.A.T. star Shemar Moore, posing with a famous former president, or feeling "alright alright alright" with Matthew McConaughey, Colbert has nothing but (selfie) love for his high-wattage guests.

The Late Show With Stephen Colbert airs Weeknights at 11:35/10:35c on CBS. Stream full episodes on CBS All Access.
