'My mum loves you' comment didn't go down well with Harrison Ford, says Daisy Ridley

Daisy Ridley offended Harrison Ford on the first day of filming 'Star Wars: The Force Awakens'.

The 23-year-old actress, who was cast alongside the Hollywood icon in the J.J. Abrams-directed sci-fi movie, has revealed how she managed to insult her co-star by revealing her mother is a huge fan of his.

She recalled: "I did say when I first met him: 'Oh my mum loves you,' and he said: 'Oh. Great'."

But once Daisy recognised that Harrison - who is reprised the role of Han Solo in the new movie - was offended by her remark, she quickly added: "Oh, I love you too!"

Daisy suffered another embarrassing on-set incident with Harrison when she mistakenly sat in his seat in the legendary Millennium Falcon spacecraft.

She told The Sun newspaper: "You have seen a couple of shots of us getting into the Falcon. I did sit in the pilot's chair and he was like: 'That is mine,' which was kind of insane."

However, the London-born star was thrilled at getting the opportunity to work with the 73-year-old actor, who she described as a "cool guy".

She shared: "It is that thing, he is Harrison Ford and is such a cool guy and a really lovely person to work with."
