Best Mistake

"Best Mistake" is a song by American recording artist Ariana Grande that features American hip hop recording artist Big Sean. The song served as a promotional single from Grande's second studio album, My Everything (2014), and was released at midnight on August 12, 2014. Written by Big Sean, Grande, and Key Wane with production being done by the latter, the song is a ballad with piano, string, and drum machine instrumentation that lyrically deals with a couple trying to decide on what their future, troubled relationship is going to be like.

Commercially, it peaked on the US Billboard Hot 100 at number 49, and within the top 50 on other record charts in North America, Europe, and Oceania. On the US Digital Songs chart, it debuted at number six, making Grande the first act since Michael Jackson, and also the first female artist, to have three songs in the top ten on that chart the same week, with the other two songs being "Bang Bang" (with Jessie J and Nicki Minaj) and "Break Free" (featuring Zedd). Grande and Big Sean have performed the song live, including at the iHeartRadio theater in Los Angeles.
