Whilst out and about in Hollywood, Heidi Montag and Spencer Pratt just happened to fall on a bed while a furniture store.

The Hills co-stars put on quite a show for the paparazzi, with some staged horizontal making-out.

They seemed so keen to keep the waiting snappers attention they even bought a few of the paps some pizza when they ate their own lunch.

The couple then took the opportunity to promote Heidi's new single by holding a bit of paper that said buy Look How I'm Doin - Heidi's new song - on Itunes.
