Rihanna has reportedly fallen for a British boxer-turned-model.

The 23-year-old singer was seen 'flirting outrageously' with Dudley O'Shaughnessy who she hand-picked to appear in the promo for her upcoming single We Found Love.

Britain's The Sun newspaper says a source on the video shoot in Northern Ireland saw the Bajan singer being affectionate with the 21-year-old former Olympic boxing hopeful.

'Rihanna was making no secret that she fancied the pants off Dudley. They hit it off straight away,' the insider said.

'She had seen his modelling shots and other pictures when he was a boxer.

'Rihanna took every opportunity to get close to him and at one point she was sitting in his lap during a break from filming. She's very tactile anyway, but this was something else.'

Dudley took up modelling after he was spotted by a scout at a London Tube station two years ago.

The 6ft tall light-middleweight was apparently dedicated to a career in boxing and wanted to be chosen for the Great Britain team competing in the 2012 Olympics before his big break came along.

'Dudley was giggling like a schoolboy when [Rihanna] had to shoot a scene in a see through top,' the insider added.

'She was teasing him with a peek at her cleavage and winking at him. Dudley can't believe his luck. Rihanna's girlfriends are teasing her, singing songs about her romance.'

Rihanna's has been linked to singer Drake, baseball player Matt Kemp and Colin Farrell since her split from Chris Brown in 2009.
