Chris Brown upset Justin Bieber during the recording of their latest single - because he was so late turning up to their scheduled session.
The R&B star collaborated with the Baby hitmaker for the second time on the track Next 2 You, following their first joint effort, Up.
But they failed to hook up in the studio - because Bieber couldn't wait for his tardy friend.
Brown tells MTV, "I actually stood him up on accident. He was kind of mad... I was all the way on the other side of town handling some business - girl business - and I was rushing back, and, by that time, he's like, 'Man, I'm leaving, bro. I did it - just check it out.' And I looked at it (recording) and listened to it and I was like, 'Man, this is crazy.' He's a great kid."
Brown insists fans will love the finished product: "Being able to collab with (Bieber) was great. He's a young, energetic cat, so being able to work with him, with the fanbase he has, was incredible. I know a lot of little girls are going to love this record."
