Malcolm James McCormick (professionally known as Mac Miller) is an American rapper. He was featured in the first single from Ariana Grande's debut album Yours Truly called "The Way".
Mac Miller and Ariana have been friends for a long time.
They did a cover of "Baby It's Cold Outside" in December 2012 which Ariana posted on her YouTube channel.
As soon as Ariana heard "The Way" she immediately thought of Miller and asked him to be on the track with her.
Ariana said in an interview that while Miller was recording his part of the song, she was upstairs in the kitchen baking him cookies.
In the end of the music video for "The Way", Mac and Ariana kiss, causing there to be a lot of speculation of a relationship.
Even more rumors circulated when Ariana and her boyfriend Jai broke up, soon after the song was released.
Ariana denied all of this saying that the kiss was directed and that she and Mac were just friends.
Ariana said in an interview with Hot 97 that Mac is one of her "best friends in the world, like in the whole world".
Mac said of Ariana, "Well [Ariana is] a very, very talented singer, like she can sing incredibly. And, that's awesome and she's a great person. She's one of the nicest just people I've ever met in my life."
