During an All Access interview with fans on MTV, Grande gave the audience the 411 on that whole situation, and went a little something like this: "I went to meet and greet with my grandparents, because my nonna has a massive crush on Justin Bieber, so I went and our fans...I think they trended #JustinandArianaSelfie or something like that. So I was like, 'We have to do this,' and Justin was like, ‘Yeah, let's take a picture.'"
Ariana continued, "So, I took my phone and I went like this [gestures selfie] and I was just smiling, and he kissed me on the cheek. I didn't know what to do. I just walked out of the room. I got shy."
However, Biebs wanted to make sure that photo was posted on the social media sites.
"Then Scooter [Braun] came after me and was like, 'Justin says you have to post that picture.' I was like, 'I will not.' And he was like, 'He says you have to post that picture.' And I said, 'I can't,' and he asked why not and I was like 'because I don't want the drama that's going to come with it.'"
Clearly, Ariana wasn't being irrational, but at one point, she posted the picture, anyway. "Then, Justin tweeted me, ‘Post that pic.' So, I just did it, but everyone was like, ‘Oh my gosh a kiss on the cheek. I'm like, can you not?' Come on!"
"You're crazy and nonna says thank you, she loves you," the 20-year-old captioned the pic, which she tweeted to the "Boyfriend" crooner and then seemingly deleted. Regardless, the twitpic was quite the hit: Within three hours, it had been retweeted 27,300 times.
After taking the snapshot down, she wrote, "Everyone, girls are allowed to be friends with guys. I'm a lady. Chill out."
In non-Bieber related news (but still concerning another young and hot singer), Grande released the music video for her single with The Wanted's Nathan Sykes "Almost Is Never Enough." Check it out below!
