Justin Bieber and Selena Gomez: Breakup On The Way?

Justin Bieber and Selena Gomez make up of the world's most scrutinized couples, so it stands to reason that breakup rumors have swirled around them from the day they got together. Up until now they've all proven false, but it seems the relationship has been so rocky in the past few weeks that even the most optimistic insiders are predicting a split in the near future.

TMZ reports that sources close to the couple have described the relationship as "not solid," adding that Justin has broken up with Selena several times in the past few weeks, but quickly changed his mind on each occasion. The couple have been together for 18 months, which is approximately 8 decades in teenager years. The source (who isn't named, of course) notes that as of right now, they remain a couple.
