Mariah Carey, Justin Bieber's collaboration leaks online

Pop star Mariah Carey's collaboration with Justin Bieber has landed online, only a few days after it was recorded.

French Montana and T I contribute to the track as well. It's a remix of her single "Infinity" and is reportedly retitled "Why You Mad?", according to Ace Showbiz.

"It's like every time you call me/ You know I can't leave you lonely," Bieber croons. " 'Cause I was always there when you need me/ Said that you'd be there til the end/ What must I say?/ I never thought it would happen this way."

"Infinity" is taken off Carey's third compilation album "#1 to Infinity".
 

Bieber showed up unannounced during the recording session and was initially not expected to take part in the remix. He eventually ended up adding his vocals and posed for a group picture.
