Wedding bets on Lara, Sam

With the year about to come to a close, the bets are already on as to which celebrity will be the first to wed in 2014 and new Aussie couple Lara Bingle and Sam Worthington are among the top contenders.

Online bookmaker Sportingbet rates the celebrity pair in fourth place at odds of $8 to head down the aisle first, despite the fact that the duo only began dating in September.

However Bingle and Worthington's declarations of love in the media and frequent Instagram snaps of each other seem to have watchers convinced a wedding is on the cards sooner or later, with one even suggesting the chance of a New Year's Eve proposal.

Former That '70s Show co-stars Ashton Kutcher and Mila Kunis are at the top of the list with odds of $3.50, while US fashionista Olivia Palermo and her beau Johannes Huebl are second in line at $5.

Speculation over the next royal wedding taking place in 2014 continues to swirl, with Prince Harry and his model squeeze Cressida Bonas at $6.

Though reports recently emerged John Mayer already refers to girlfriend Katy Perry as his "wife", the couple were the outsiders in ninth place at odds of $11.

Australian actress Rose Byrne and her Annie co-star Bobby Cannavale rounded out the list at $12.
