Los Angeles: A new track featuring singers Mariah Carey, French Montana and Justin Bieber is underway.
The songstress revealed the collaboration when she posted on Friday, an Instagram photograph of her posing with the rapper and the pop superstar in what looks like a recording studio.
"#comingsoon," she captioned the image.
According to tmz.com, the image was taken on Thursday night at a Hollywood studio where Carey and Montana were working on a song with producer Eric Hudson. Bieber later showed up unannounced and told Carey he's a huge fan of her.
The veteran diva then played him the new song and the Canadian heartthrob reportedly liked what he heard. So, he decided to go into the booth and recorded some guest vocals, which will likely be featured on the final version of the track, reports aceshowbiz.com.
During the same studio session, Carey took another photograph with Montana.
She also shared the image with her Instagram followers and said, "We love @frenchmontana #pondestudio #surprise."
This isn't Carey's first time to have recorded a song with Bieber as they previously worked together on a duet of her classic "All I want for Christmas is you" for his 2011 holiday album "Under the mistletoe".
