Cara Delevingne criticised for snubbing Formula 1 interview, says she was told to say no

Planet Sex presenter Cara Delevingne has been criticised for "absolute garbage behaviour" after snubbing Formula 1 TV presenter Martin Brundell live on television.

Brundell was at the British Grand Prix at Silverstone on Sunday (UK time) and was interviewing people he'd seen down on the racetrack prior to the event.

When he saw the supermodel, he walked over and asked if he could have a chat with her about the race.

Despite initially smiling at Brundell, Delevingne turned him down, with her assistant telling him it was a no.

"She doesn't want to talk but everybody has to talk on the grid, that's the deal now, everybody talks," Brundell protested.

Persistent, he pushed by her security and said: "Can we have a quick chat, Sky F1, good to see you on the grid."

She responded with "no" before telling him she couldn't "hear anything, I'm so sorry".

As Brundell walked off, Delevingne could been seen giving what appeared to be a triumphant fist pump while smiling.

Brundell then told viewers sarcastically: "OK well I'm sure it would have been extremely interesting."

Delevingne's actions have been slammed online.

"SO bloody rude! Showing her true colours here - a privileged spoilt brat who has had everything handed to her on a plate so she really does not appreciate being there!" said one tweet.

"Says no to an interview, then proceeds to say she can't hear anything?" another questioned.

"Cara Delevingne, absolute garbage behaviour. You're on the grid, talk to Martin Brundle,"  another angrily wrote.

However, the actress has taken to social media to respond to the furore, explaining what happened.

"I was told to say no so I did," she wrote on Twitter.

"It wasn't an agent, it was an F1 representative," she explained to further commenters.
