Boyzone star Ronan Keating and wife, Yvonne are the hot celebrity favourites to split up in the New Year 2012.
The pair are followed closely in the 'split' betting by engaged Westlife star Marcus Feehily and his fiancé, Kevin McDaid.
Ronan and Yvonne, who reunited after announcing their separation last year, are least likely to survive until the end of the year according to the bookies' odds.
The two, whose marriage was shaken by Keating's affair with a Boyzone dancer, are set to be the first to split with odds of 13/8 according to Paddy Power bookmakers.
"They've had their troubles in the past and no one ever suspected anything for ages," said Sharon McHugh of Paddy Power. "Even though they look very strong right now, their relationship has already been fractured so it's more fragile than most."
Westlife singer Marcus Feehily claims that he plans to marry fiancé, Kevin McDaid in 2012. However, the couple are also 7/4 to split according to Paddy Power.
"They are second favourite only because we've had people call us especially to request odds on them splitting," she said. "Apart from that, we don't really know anything about the relationship because they keep to themselves and they live in the UK."
Former Westlife star Brian McFadden and Vogue are third favourites in the betting to hit the rocks in 2012 despite rumours of an imminent engagement.
"They're third favourite because of fears this is a rebound relationship for Brian," said Ms McHugh. "He broke off his engagement with Delta Goodrem and it seemed within weeks he had thrown himself into a relationship with Vogue."
Fourth in the betting is former Miss World Rosanna Davison and Wesley Quirke at 6/1. "They're together for ages but there's no progress - Wesley needs to present a ring!" said the spokesperson.
Others in the betting include footballer Robbie Keane and wife Claudine at 10/1 and superhoofer Michael Flately and wife, Niamh at 12/1.
Outsiders in the betting are new parents Kian Egan and Jodi Albert, newly weds Pippa O'Connor and Brian Ormond and childhood sweethearts, Nicky Byrne and Georgina Ahern.
