17-year-old pop singer, Justin Bieber, has been dating singer/ actress, Selena Gomez, 18, for several months. They've been, er, dueting off stage. But will they duet on stage as well. The star of "Never Say Never" has a number of irons in the fire, will this be one of them. 

This could work for them or spectacularly blow up in their faces, if Bieber's audience, who've already been threatening to slap Gomez into next week for dating their boy, disapprove of a musical union. 

Why did I write that, you ask. No reason. Just thinking out loud...or maybe I'm sadistic and would laugh at poor Gomez getting pelted with fruit by Bieber Nation, while attempting to sing with him on stage. You decide.
