Do-it-yourself Duffs Turn Trailer Into A Kennel Club

Duff sisters Hilary and Haylie saved their producers a fortune on the set of their new film Material Girls - by insisting on sharing a trailer.

The siblings refused to 'live' in separate trailers on the set and asked to be paired up with their pet dogs.

The plan worked until the Duff girls added a cardboard dog kennel.

Hilary explains, "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 adds, "It just kind of took up a lot of room."
