Los Angeles, May 19 : Pop singers Miley Cyrus and Justin Bieber are reportedly planning to collaborate for something new.

Cyrus, 20, was spotted leaving a Hollywood recording studio within minutes of 19-year-old Bieber Thursday.  They are believed to be working on a collaboration, reports contactmusic. com.

"There aren't that many recording booths at this studio, they must be doing something together.  Justin and Miley left within minutes of each other - it's too coincidental.  There's gotta be a collaboration in the works," said a photographer from X17online. com.(IANS)
