Is the "King of R&B" R Kelly collaborating with Justin Bieber? According to our source, Kellz talked with VIBE last night, while promoting his upcoming album Black Panties, and confirmed he has.
"I just did a song [with him.] [Justin] just called me to do a song and it's hot. He wanted to go and do some R&B stuff so we got together and did that."
Kellz also went on to say that he's at his best one-on-one and he's willing to work with anybody.
