Odds offered on first Girls Aloud pregnancy

Bookmakers Paddy Power are offering odds on which member of Girls Aloud is most likely to get pregnant first. 
 
Ireland born Nadine Coyle is the marginal favourite in the running, with punters being asked to back her at 2/1. Coyle is narrowly ahead of X Factor and Geordie goddess Cheryl Cole, who recently confessed she and her footballer husband Ashley Cole are ready to have a baby. Cole is the next best beauty at 5/2 with Paddy Power.
 
Interestingly, blonde bombshell Sarah Harding is the least likely to have a baby first according to the odds, which would perhaps mirror her partying reputation. Harding is the 6/1 outsider despite being in a long-term relationship with DJ Tom Crane.
