Did Biebs's Partying Ruin Jelruin Jelena 2.0?

Trouble is back in paradise for the reunited lovers...

Is it too late now to say sorry? That’s what Justin Bieber may want to start singing to girlfriend Selena Gomez as talk of yet another split reaches fever pitch.

Indeed, the couple – who’ve been dubbed a modern day Romeo and Juliet due to their drama-plagued relationship – have only been seen in public together once in the last 29 days.
