The rugby star has revealed he literally picked Una off the television as the girl he wanted to be with.
27 year-old Ben told a UK magazine that he had spotted the Saturdays singer on the TV before asking his agent to put in a call.
He said: ‘I'd been having lunch in a pub with my agent when he asked about my love life, and I was, 'Oh, non existent.'
'The Saturdays popped up on the music channel in the corner, and I said, 'Oh, the one with the blue tights'
‘He asked me if there was anyone I was thinking about, then The Saturdays popped up on the music channel in the corner, and I said, 'Oh, the one with the blue tights.’
The rugby player continued: ‘And the next thing I know, I've got a text saying, 'She's expecting your call.'"
The pair later married in June 2012 and became the proud parents of their daughter Aoife Belle - who recently celebrated her first birthday.
'His agents went behind his back and asked if I'd go on a date with him'
Meanwhile, Una, 31, announced in her new magazine column that the loved-up pair will be making an appearance on TV show Mr and Mrs - and spoke out about that fateful phonecall.
She wrote: ‘Ben and I got married last July and we’d been together for about three and a half years before that. The story of how we met is quite funny…
‘I was introduced to him after his agents went behind his back and asked if I’d go on a date with him. They got my number and passed it on to Ben who then called me. That was it really!’
