Melissa McCarthy returned this week to host [1] Saturday Night Live [2] for the fifth time, and she kicked off the show by giving a mom from the audience a tour of the studio in honor of Mother's Day [3]. While giving Joan a tour of the backstage area, the duo ran into some famous friends — Blake Lively [4] and Ryan Reynolds [5] (or, as Melissa calls them, "the Livelys"). Still, the real star may have been the infamous SNL hallway llama [6], who also made a quick cameo in the skit.
