AceShowbiz - Ariana Grande and Big Sean's friendship first started when the latter was featured on the singer's 2013 single "Right There". But given that both of them were romantically linked to other people at that time, no one suspected that they had moved past the friendship stage, until the collaborators released another joint single, "Best Mistake", in 2014.
Both Ariana and Sean were single when they released the song, so it didn't take long for people to start speculating whether they had taken their friendship to the next level. At first, the pair played it coy and said that they were "just friends," but judging by their Instagram flirting and surreptitious hand-holding, the rumors didn't die down just like that. Ariana finally confirmed the rumors during an interview in October 2014, before they split up amicably a year later.
