Normally wedding photos are invite-only - you'd better be a bride, a groom or a member of the wedding party if you want to get in.
But when you're the Prime Minister of Canada, the couple might make an exception.
Jocelyne Potvin and Patrick Sullivan got married this past weekend. While photographer Laura Kelly was snapping pics of the couple and their party, three dark cars pulled up.
"Someone jokingly says, 'I bet you it's the Prime Minister or something,'" Kelly recounted on her blog.
The group laughed and carried on with their picture taking.
And then the Prime Minister stepped out of one of the cars, along with his security detail.
He headed over to congratulate the couple, and agreed to appear in a couple of shots with them.
He also asked the groom "so, have you already done it?" Patrick, assuming Harper was asking whether this was their first marriage, responded "Nope, first time!"
It turns out the PM was asking whether the ceremony had taken place.
Before he left, Harper also posed for a picture with the photographer, taken by the bride. Here's Stephen Harper and Laura Kelly:
So there you have it. Two things you didn't know about our Prime Minister: he's into photobombing, and he rocks a blue windbreaker when he's out on the town.
And if the PM wants to take his life in front of the camera a little further, here's a humble suggestion for the movie we'd all love to see:
