13 of the Youngest "Saturday Night Live" Hosts of All Time

Taylor Swift was a month away from her 19th birthday when she served as musical guest and host on "SNL" in November 2009. Her hosting gig came months after she made her "SNL" debut in January of that same year. In total, she's been musical guest six times and even appeared on the show's 40th anniversary special, but she hasn't hosted since. In her iconic "Monologue Song," she joked about her then-recent breakup with Joe Jonas and her then-new feud with Kanye West.
