Are Justin and Miley in the studio together?

Blonde, spikey hair might not be the only thing these two stars have in common- they may also have a song in the works! After Miley Cyrus was seen leaving a studio in L.A. where Justin Bieber was said to be recording, fans couldn't contain their excitement about a possible collaboration. "You guys will have to wait and see," Miley says. "I'm the biggest at top secrets. I've had this single ["We Can't Stop] ready for about a year and had to keep my lips sealed." Fingers crossed, Jiley!
