In a recent performance by Ariana Grande, Justin Bieber joins her on stage to perform a few of her pop hit songs. During their concert interaction, Bieber grabs onto the “Problem” singer, which seemed to create some problems for Grande’s boyfriend Big Sean. It appears that after the show, Big Sean took to Twitter to voice his issues with the exchange. From the looks of it, the touchy-feely moment seemed innocent, but to the “Blessings” rapper, it may have been blown a bit out of portion. According to sources close to Bieber and Big Sean, the two men are friends and the exchange on stage has not created any problems in their friendship.
