The singer and actor met on the UK TV chat show 'The Graham Norton Show' around Christmas last year and they exchanged phone numbers and have reportedly been 'sexting' shortly after that.

A source said that, "Colin was taken aback by some of the texts. He reckons he might well be in there. They're both single, so why not?"

It is reported that on the show, Farrell had complimented Rihanna's legs saying, "They are very nice limbs. There's probably a reason I mentioned them, I had to get them off my mind."
