"Bloooooody hellllll I’m so excited about this!! And also absolutely terrified!" the GRAMMY winner wrote. "My first ever hosting gig and for SNL of all things!!!!"
She also explained why she'll be serving strictly as the host, and not the musical guest as well.
"I’ve always wanted to do it as a stand alone moment, so that I could roll up my sleeves and fully throw myself into it, but the time has never been right," she shared. "But if there was ever a time for any of us to jump head first into the deep end with our eyes closed and hope for the best it’s 2020 right?"
SNL airs live, coast-to-coast, at 11:30 p.m. ET, 8:30 p.m. PT on NBC.
