R&B superstar Ariana Grande was the headlining performer for the 2015 NBA All-Star Game at New York’s famed Madison Square Garden on Sunday night (Feb. 15). The show featured plenty of choreography and one very special guest.

Dressed in a black-and-white cheerleading-style miniskirt, bra and stilettos, the pint-sized vocalist belted out six-song medley of her chart-topping hits. Backed by her dancers, Grande performed "Problem" before seguing into her most recent Top 10 hit, "Love Me Harder."

The 21-year-old songbird had the lights dimmed for her rendition of "One Last Time," her latest single. But Grande had one big surprise up her sleeve. During her performance of "Bang Bang," she brought out Nicki Minaj who hurriedly rapped her verse from their collaborative tune sans Jessie J. The Queen Barbz and Grande briefly grinded on each other before they parted ways.

Finally, Grande closed out her 12-minute set with a stellar performance of "Break Free."

Afterward, Grande and Minaj continued their love fest on Twitter. You can read their tweet below.
