SNL is one of those shows that changes a lot depending on the host and musical guest, but in many ways, it doesn't really change all that much if you think about it. There's usually a cold open. There's a monologue.

Morgan Wallen was this weekend's musical guest on "Saturday Night Live," where he performed "I'm the Problem" and "Just in Case." However, the country singer was spotted whispering in host and Oscar-winning actress Mikey Madison's ear as she closed out the show onstage before he abruptly walked in front of the NBC camera and appeared to leave.
