Pop singer Ariana Grande is set to perform at halftime of the 2015 NBA All-Star Game at Madison Square Garden on Sunday. The Florida native will reportedly be performing with a surprise guest at the annual basketball event.

Nicki Minaj, who has been spotted during much of the festivities of All-Star Weekend, has been speculated as a possible guest performer. Pop star Rihanna was also seen during the event.

Grande told her over 25 million Twitter followers that her "One Last Time" video will debut at midnight on the East Coast. The 21-year-old has been mum on Twitter in recent days about her appearance at the All-Star Game.

Prior to the start of the 2015 NBA All-Star Game, singer Christina Aguilera performed. The national anthem was sung by Queen Latifah.

The All-Star Game has often showcased musical acts. The 2014 NBA All-Star Halftime Show in New Orleans featured Earth, Wind and Fire along with singer Janelle Monae.
