Ariana Grande did a nice job as host of Saturday Night Live this weekend. Except for that bizarro wardrobe malfunction she fumbled with while performing her new song "Dangerous Woman."

The 22-year-old pop star apparently needs a little practice in jacket-wearing, especially the part about how to put it on. It's a stunt she tried in the middle of her number but seemed to have trouble with, leaving her with a single sleeve dangling for the rest of it … first one one side and then on the other.

You can see all the hilarity for yourself …
