Now that's how you start the show!
But just as we're catching our breath from singing (and dancing) along, the talented ladies have decided to release the official music video for their hot new single. Watch the video right here!
"It's me starting a street party that Ariana is then going to attend, and then Nicki turns up on an amazing type of transport, that I won't give away," Jessie J recently told MTV News about the video. "And then we all party together on a rooftop and there's loads of dancers, there's a dance that you can learn that I made up."
Featuring impressive outfits, killer moves and amazing scenery, the video certainly doesn't disappoint.
We also still can't get over the killer vocals and impressive rap from Minaj.
"Bang Bang" is the debut single from Jessie's upcoming album. It will also be featured on the deluxe edition of Grande's album, My Everything, available Monday.
Tune in Tuesday, Aug. 26, at 8 p.m. for a special VMA and Emmys edition of Fashion Police!
