Katy Perry is turning out to be quite the diva.
The singer gets together with Keri Hilson and Jennifer Nettles for an all-star performance of "Boogie Woogie Bugle Boy" for the upcoming "VH1 Divas Salute the Troops." For the salute, they join Sugarland, Nicki Minaj, Paramore and more to perform from military bases around the world. Watch the video to hear Katy tell ET about being a diva!
The always outrageous Kathy Griffin will host the special, airing Sunday on VH1. Although she's known for her wicked sense of humor, she's surprisingly serious about entertaining the troops.
"After having had the honor of performing for our troops in Iraq and Afghanistan, it gives me great pleasure to host an evening for them where they can really blow off some steam," she says. "I will not hold back ... It's going to be a wild night of great music and a heartfelt thank you."
