Liz Hurley's romance with cricketer Shane Warne is the shakiest in showbiz, according to a leading UK bookmaker who is predicting the couple will be the first to split in 2012.

Katy Perry and Russell Brand previously topped the William Hill bookmakers break-up list -- but the British funnyman filed for divorce in the final days of 2011, ending that bet.

Now Hurley and Warne are the showbiz couple next likely to part ways with odds of 4/1, according to William Hill.

Take That star Jason Orange is on 8/1 to part from comedienne Catherine Tate, and 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 is 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 2012, 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.
