T4 presenter Alexa Chung has been linked to Keira Knightley's ex-boyfriend Jamie Dornan.

Alexa was spotted looking cosy with the model at the V Festival at the weekend, after he approached the host and started to flirt with her.

An onlooker told The Mirror: "As soon as Alexa sat down, Jamie made a beeline for her and proceeded to flirt outrageously."

A recent report revealed that Alexa was involved in a relationship with Lostprophets singer Ian Watkins.
