The former Spice Girl was a very close friend of the late music star.
Robbie Williams broke a fan's arm after falling off stage during a recent concert.
The singer was in the middle of his 'Swings Both Ways' show in Newcastle, when he lost his footing as he leaned out to greet fans.
According to The Mirror newspaper, Margaret Nash was left with a broken arm after Williams landed on her.
Arena general manager Paul Tattenden said: "We attended to the lady after she said she had pain in her arm.
"We were later told she had broken it. We got in touch with Robbie's production company and they have been in touch with the lady."
Williams was not aware of her injury during the show.
