Mandy Moore and Ryan Adams – This married musical duo always seemed like a rather strange pairing. Before going indie, Mandy was the anti-Britney, the sweet pop princess who could actually sing and didn't use sex to sell records (and consequently, she never sold as many as Brit). And before his "indefinite hiatus" from music, Ryan was a moody, bad-boy alt-country rocker. Therefore, we think Mandy and Ryan could perfectly portray another well-known couple that started out on opposite ends of the tracks and met in the middle – Grease's Sandy and Danny. Of course, if they want to play against type, Mandy could get wild as a dominatrix with Ryan as her slave boy!
Demi Moore and Ashton Kutcher – Since these two are close pals with Demi's ex, Bruce Willis, maybe they could have a little fun with that and go to their Halloween party as Maddie and David from Bruce's old series, Moonlighting? Or, for a little role reversal (and one that doesn't require Demi to cover up her gorgeous, long brunette locks with a short blonde wig), they could masquerade as another famous couple, Catherine Zeta Jones and Michael Douglas. We're sure Demi would enjoy being the younger woman for one night – and the ageless star wouldn't even need makeup to achieve that look!
Ellen DeGeneres and Portia De Rossi – In a nod to Ellen's new gig as American Idol's fourth judge, these two could do the Transylvania Twist dressed as Simon Cowell and Ellen's AI predecessor, Paula Abdul. (We'll let them fight it out over which one gets to be Simon.) Or, since they both have blindingly blonde hair, perhaps they could be two of those creepy kids from Village of the Damned? All they'd really need are matching dresses and some white contact lenses.
Kristen Stewart and Robert Pattinson – No doubt these two are looking forward to Halloween; donning costumes might be their only escape from the daily routine of flashing cameras and crazy fans hounding them. Obviously, they should stay away from anything resembling vampires, werewolves, damsels in distress, etc. Their best bet might be the good old-fashioned standby – the ghost. Throwing some sheets over themselves would certainly be a good way to make sure no one knows who they are. But if they want to have more fun (and get in a little jab at the tabloids), they could enlist Robert's rumored ex Nikki Reed and all go as Chrissy, Janet and Jack from Three's Company! Can you imagine how the Twi-Hards would react to seeing Robert in terrycloth short shorts?
Heidi and Spencer Pratt – There are a number of appropriate options for these two: a couple of clowns, Tweedledum and Tweedledee (Alice in Wonderland), or Thing 1 and Thing 2 (The Cat in the Hat). But for something much more elaborate and suitable, they could double date with Khloe Kardashian and Lamar Odom and be the Four Horsemen of the Apocalypse. (Costumes optional!)
