Emily Longeretta Ariana Grande wasn’t just the musical guest during the March 9 episode of “Saturday Night Live.” While she took the stage to perform “We Can’t Be Friends” and “Imperfect For You” — and was introduced by her mom, Joan Grande, for the second number — she also took on two different sketches. After appearing as a patient in a group therapy session during the first half of the show, she was invited back to the stage later on in the night for a “Moulin Rouge” spoof, giving her the opportunity to sing covers of multiple hit songs.
