Bob Watch: Jenna Malone gets final cut!

OK, last one on the Bob Bandwagon is a loser.

That would be Jenna Malone, who turned up at the premiere of "The Ruins" in L.A. last night wearing yet another copycat Katie Holmes/Louise Brooks cut.

OK, Jenna, gently put the scissors down and step away, slowly. This bob-mania must end now. If you turn yourself in, we will get you the hair help you need.

Now, for the citizen's arrest. What do you think of Jenna's bowl cut? Vote NOW!
