Justin Bieber and R. Kelly have recorded a single together.
The 'Never Say Never' singer will release the collaboration on Monday as part of his Music Mondays series.
R. Kelly told Vibe magazine: "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."
Justin's fans were over the moon with the news, with one tweeting: "This is too much for my weak heart."
The title of the track - the seventh in Justin's series of reveals, which have mostly been mid-tempo tracks about love and heartbreak - is yet to be announced.
R. Kelly hopped into the studio with the teenager after his collaboration with Lady Gaga on the track 'Do What U Want', which features on her new album 'Artpop'.
The 'Ignition' singer recently shot a video for the song with Miley Cyrus's photographer.
Lady Gaga said: "I shot it last week with Terry Richardson, and R. Kelly's in the video.
"We had a great time. It was amazing. He's wonderful to work with."
