Ariana Grande performed at the NBA All-Star Game halftime show this weekend—and she pretty much killed it. A few places on the 'net have chided Grande's dry, almost stiff dancing style, but when you take into consideration that (it looks like) she's not lip synching, and stayed in almost perfect tune the whole time, it's hard to not be impressed.
The performance also includes a "surprise" appearance by Queen Nicki Minaj.
