Rumours of Prince Harry's romance with American actress Meghan Markle have seen bookmakers tempting punters with odds on when the couple will first appear together.
Harry has been an eligible bachelor since he split from long-term girlfriend Cressida Bonas more than two years ago.
And now he has been linked with Markle - a star of hit US TV show Suits - with the pair spotted wearing the same bracelet.
Paddy Power has odds of 5-2 the Prince and the actress will appear together at the traditional Royal Christmas church service at Sandringham.
William Hill believe seeing the two of them in church with the Queen over the festive period is a long-shot at 50-1, but are offering odds of 5-1 the pair will watch international rugby at Twickenham in a royal box, during a six nations or autumn international match.
The Sunday Express reported the pair met in May while Harry, 32, was in Canada promoting Invictus Games Toronto 2017, the paralympics-style competition for injured servicemen and women and veterans he founded.
Markle is thought to share Harry's love of Africa, a continent he visits regularly both privately and to promote his charity Sentebale, and where his rumoured love interest has carried out humanitarian work.
Since Harry split from Miss Bonas in 2014 he has been linked to a number of women including singer Ellie Goulding and Camilla Thurlow.
Paddy Power is offering odds of 6-1 for the prince and actress to get married in 2017, while William Hill are not as convinced Markle will snare Britain's most eligible bachelor and have odds of 25-1 on a royal engagement.
A Paddy Power spokesman said: "Prince Harry's romantic endeavours would be more at home on an episode of Suits but after several high-profile break-ups it seems he might have finally met the one.
"The fifth-in-line to the throne isn't getting any younger and is rumoured to be desperate to settle down so it would come as no surprise to see the pair get hitched next year - I'll await my royal invite."
William Hill spokesman Rupert Adams said: "It looks like very early stages here and any hope of an engagement looks a serious long-shot.
"Although we have a sneaky suspicion that Harry might take Meghan to a rugby match as their first public outing."
Kensington Palace has said it will not comment on private matters and Markle, a regular user of social media, has not confirmed or denied the reports since they emerged.
