Last night (April 7) was the grand opening of the T-mobile Arena in Las Vegas, and to celebrate the big day, Nicki Minaj and Ariana Grade took the stage together.

They kicked things off with their Jessie J-assisted smash-hit “Bang Bang” as well as their Pinkprint collaboration “Get On Your Knees” for the very first time. The queen of rap then continued with “Anaconda,” “Super Bass,” and “Starships.”

T-Mobile’s CEO John Legere spoke about having the two ladies hit the stage together by saying: “What better way to open this amazing arena than with two amazing artists — Nicki Minaj and Ariana Grande — and a few thousand customers and friends?”

The brand new T-Mobile 20,000-seat venue is located near the famous Las Vegas Strip and capable of holding large scale concerts, UFC fights and award shows.
