Rihanna 'sexting' Colin Farrell?

Rihanna has reportedly been sending Colin Farrell a deluge of sexy text messages.

According to The Sun, the 'S&M' singer has been in constant contact with Farrell since meeting him before Christmas when they both appeared on Graham Norton's chatshow.

After swapping numbers, Rihanna is said to have repeatedly sent flirtatious messages to the actor.

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

Farrell ended his relationship with girlfriend Alicja Bachleda-Curus, with whom he has 16-month-old son Henry, late last year.

Rihanna, meanwhile, split from baseball player Matt Kemp after dating for around a year.
