Katy Perry Signs Divorce Papers w/ Smiley Face

Either she's SUPER EXCITED to be divorced that she included the "smiley" face in her signature, or she's just so used to autographing her name that she didn't even notice. Either way, Katy Perry kept the emoticon in her signature on her divorce papers last week.

I wonder if Russell Brand used any other popular faces? Maybe a ;-*( face?  [BettyConfidential]
