The 46-year-old singer made a cameo in a sketch that saw host Peter Dinklage, also 46, play an '80s-style New Wave singer who sings a song titled "Space Pants" at a restaurant, which distracts a group of mobsters, made up of cast members Beck Bennett, 31, Bobby Moynihan, 39, Jon Rudnitsky, 26, and Pete Davidson, 22. Stefani then joins Dinklage onstage, wearing sexy "space shorts."
"Hey @gwenstefani... Please wear space pants when you get back home!!! Ha!!!!" tweeted Shelton, 39.
