Elizabeth Hurley's romance with cricketer Shane Warne is the shakiest in showbiz, according to a leading U.K. bookmaker who is predicting the odd couple will be the first to split in 2012.
 
Katy Perry and Russell Brand previously topped the break-ups list for William Hill experts, who slashed the odds on their love split in 2012 from 6/5 to 10/11 - but the British funnyman filed for divorce on Friday, thus ending that bet.
 
And now actress Hurley and her sportsman fiance are the showbiz couple next likely to part ways with odds of 4/1, according to William Hill bookmakers.
 
Brad Pitt and Angelina Jolie - along with parents-to-be Beyonce and Jay-Z - are at 25/1 to join the broken homes club.
 
But Prince William and his new bride Catherine, Duchess of Cambridge, have a rock solid romance - William Hill bosses are offering odds of 100/1 on them splitting and just 2/5 on them announcing the first celebrity pregnancy of 2012.
 
In other predictions by the bookies, Lindsay Lohan is 11/10 favourite to be the first star arrested in the New Year, followed by British rock wildman Pete Doherty at 5/2, troubled Courtney Love at 4/1, George Michael at 6/1, and Charlie Sheen at 8/1.
