Pair introduced by 'wannabe Cilla Black' Alexa Chung, according to a source

KlaxonsJames Righton is dating Keira Knightley, according to one red top at least.

The couple have been enjoying romantic strolls around London since being introduced by mutual pal Alexa Chung around four weeks ago, a source told the Sunday Mirror.

The mole compared Alexa to ’90s TV matchmaker Cilla Black and said that Keira is “extremely happy” with the singer/keyboardist.

“He’s a real rocker and a lovely guy with it and she likes that whole scene – lately she’s [Keira] become far more rock and roll and has been hanging out with a really trendy crowd,” the source commented.

However, Keira – who split from boyfriend Rupert Friend earlier this year – apparently wants to “take things slowly” with Righton.

Which means we’ve been told not to expect to see them appearing together on any red carpets any time soon…
