I should be ashamed of myself for not remembering it was Gerard Butler’s 41st birthday on Saturday (November 13). Shame on me! Gerard took over new restaurant The Darby (which opens to the public on Wednesday) on Saturday night with a bunch of friends and actually sang Mustang Sally onstage with John Mayer.

The celebrations included a dinner and performances for over 100 guests that included Kate Hudson, Jason Statham, Bono and Jay-Z. Not to sound like a freaking ingrate, but who the hell does a girl have to sleep with to get Jason Statham and/or Bono at her birthday party?

Page Six is reporting that:

Australian comedian James Smith toasted Gerry. He then went on to make fun of him saying: ‘Gerard has been out so much he’s now just constantly on Page Six. Gerry is on Page Six so much they have to make it Page Seven.’ Smith also joked that Butler and Jennifer Aniston had “as much sexual chemistry as Regis and Kelly” in “The Bounty Hunter.”

Ouch. I would have loved to see Gerard’s reaction to that jab. Apparently Gerard also sang Oasis’ Wonderwall and word is he has an ‘epic’ voice! Why does that not surprise me? I’ve long imagined hearing his voice whisper in my ear and it was very musical. And by musical I mean dirty. Very dirty.

Happy belated birthday Gerard.
