Fan On Stage With Keith Urban

Is this becoming an epidemic?  I'm talking about fans jumping up on stage and actually thinking the performer would like to dance with them.  They don't.  Anyway, so far this year we've seen it happen to DARIUS RUCKER and LUKE BRYAN.    --This time it was KEITH URBAN being approached by a somewhat luscious young lady who was quickly hauled away by security.  (--She suddenly appears at the 22-second mark.)
