Thinking about this some more - would Zoey's man be up to a revenge video where the mess is dished out by Marcy and Brittany as "punishment" for getting Zoey pregnant.
I think what would be a brilliant shoot is having a number of cakes. Start off with her pushing her pregnant belly into a cake squashing it flat. Then some cake sitting - those cakes wouldn't stand a chance, then maybe smashing a couple cakes with her boobs.
