Wat's that movie like a disaster movie where the heroes are red-headed girl and a blond british guy?

i just saw this movie now on mbc persia and it came right before the movie flashpoint and i missed the name of that movie it was so funny and i think it was a disaster movie cuz in it they were making fun of how on her weddding day the girl got a huuuge zit and then her husband is waiting for her and his watch sais "she's late" and he's standing next to a thin blondie who's trying to convince him that she's for him.. in teh end the couple gets married in by a small black dude and they go away in a carriage then they are filminga hollywood horror movie and the victim is the blondie ...
