Other than the scary as all hell giving birth scene, this movie is one you can watch over and over again. It stars Katherine Heigl as Alison, an ambitious journalist who has a one-night stand with layabout Ben (Seth Rogen), and only goes and gets herself, well, eh... clue is the title. The pair decide to give their relationship a go for the baby's sake, and sure it all gets pretty hilarious at times so it does. It's comedy gold, but there's a genuine heart to this movie as well, but again, maybe fast forward the child birth scene, if not, your reaction will probably be along the lines of... 'Jayysuuus'. We warned you.
