Uh-oh, looks like The Lylas might not have a name.  Bruno Mars' super hot sisters also have a group called The Lylas (who knew?) and they don't want to share the name with The Lylas from X-Factor.  [TMZ]
I say, make them have a head-to-head sing-off!  The winner gets to keep the name! 

On A Bruno Mars Note...

Bruno MArs has revealed the artwork for his highly anticipated "Unorthodox Jukebox" due out in Decemeber!!  I'm asking Santa for this in my stocking Wink
