Hilary and Haylie Duff saved their producers a fortune on the set of their new film Material Girls - by insisting on sharing a trailer.
Hilary and Haylie refused to 'live' in separate trailers on the set and asked to be paired up with their pet dogs.
The plan worked until Hilary and Haylie added a cardboard dog kennel.
Hilary Duff said:
We had some big thing delivered in a big cardboard box, so one day we were bored and we cut it up into a dog house and we painted pictures all over it. 
So we had this random cardboard box as a dog house, but the dogs never used it. 
Haylie Duff added:
It just kind of took up a lot of room.
