Keira Knightley is dating Klaxons star James Righton, according to reports.

The pair are said to have begun seeing each other after being introduced by mutual friend, TV presenter Alexa Chung.

A source told the Daily Mirror that the Pirates Of The Caribbean star, who split from long term boyfriend Rupert Friend earlier this year, is "extremely happy" with her new man.

"He's a real rocker and a lovely guy with it and she likes that whole scene - lately she's become far more rock and roll and has been hanging out with a really trendy crowd," the source added.
