The collaborators were reportedly spotted kissing during a late-night showing of The Purge at The Grove in Los Angeles just weeks after Grande called it quits with her 19-year-old boyfriend Jai Brooks. Sean recently called off his high profile engagement to Glee star Naya Rivera, who recently shocked fans by tying the knot with actor Ryan Dorsey in a surprise ceremony. It was rumored that Rivera’s wedding fell on the same date that she was supposed to have married Sean.

"Best Mistake" is the third song to be released off Grande's forthcoming sophomore album, My Everything, following the Iggy Azalea-assisted "Problem" and "Break Free" featuring Zedd. Listen below.
