It’s not every day that you have the famous Gerard Butler crashing a hen party.

But lucky bride to be, Maja Nogic managed to meet the Scottish actor after she spotted the star at Sydney docks last weekend.

After posing in some pictures with the bride to be, Butler asked could he join the group: “Is this a hen party? Can I join? We’re going to dance a little bit, drink a little bit.”

One of the friends of the bride said they got “the shock of their lives” when they saw him and initially confused the famous star for a stripper.

Gerard is in Sydney preparing to shoot for Alex Proya’s film Gods of Egypt.
