Becky's life is blooming! She's working at London's newest fashion store The Look, house-hunting with husband Luke (her secret wish is a Shoe Room)... and she's pregnant! She couldn't be more overjoyed - especially since discovering that shopping cures morning sickness. Everything has got to be perfect for her baby: from the designer nursery... to the latest, coolest pram...to the celebrity, must-have obstetrician.

But when the celebrity obstetrician turns out to be her husband Luke's glamorous, intellectual ex-girlfriend, Becky's perfect world starts to crumble. She's shopping for two... but are there three in her marriage?
