Pink is a certifiable bad ass.  Not only does the singer talk the talk, but she really does walk the walk!  We spotted Pink leaving the Four Seasons in Los Angeles last night.  A posh hotel might not hold the same street cred as a biker bar but hoping onto a Triumph motorcycle definitely proves that she’s a tough broad. 

Between Pink and Madonna today, who’s the tougher chick?  I personally wouldn’t mess with either!
