Watch Ariana Grande Star in 'SNL' Promos

Ariana Grande is prepping for 30 Rock. Ahead of her hosting and musical performance duties on “SNL” this weekend, the songstress stars in a series of promos for the big show.

In the comedic clips, “SNL” cast member Taran Killam joins Ari and jokes about the singer’s last name, cumulus clouds, her height, and her “Problem” lyrics.

“Are you saying ‘Prom Production?'” the “Focus” star asks Killam after he tries singing “Problem.” “I don’t blame you. Enunciation is my forte. But it actually is the title. ‘I got one less problem without you.'”

In addition to hosting, Grande will debut two new songs off her upcoming third album, Dangerous Woman, “Be Alright” as well as the title track, which will be available on iTunes Friday.
