Kerry Katona left fans shocked as she reportedly revealed live on stage that she once kissed Robbie Williams.

The former Atomic Kitten star, 45, was appearing at London’s Clapham Grand alongside Katie Price for their live show.

Many a bombshell has been dropped at the live shows, with Katie recently revealing she once snogged rapper Eminem.

Now Kerry has opened up about her own celebrity flings, revealing the most famous she’s ever kissed is singer Robbie.

A source told The Sun: ‘Kerry was having some banter with an audience member last night and he asked who was the most famous person she kissed.

‘She revealed it was Robbie Williams! She was telling the crowd it was before he married Ayda [Robbie’s wife] and it was “When she was young”.

‘Everyone was gasping at her confession!’

The Daily Mail has contacted Kerry’s representatives for comment.

However it’s not the first time Kerry has opened up about the night she spent with the former Take That star.

She said in her new! column in 2020: ‘Apart from Brian [McFadden), the closest I’ve got to a big celebrity s**g is Robbie Williams, no less, we met backstage at Saturday Night Takeaway, soon after my split from Brian.

‘Rob obviously took a shine to me as he asked if he could come to my hotel room that night.’

Kerry said at the time that she was nervous and called her mother to ask if she should shave in case the pair became intimate.

She insisted there was ‘no funny business’ between her and Robbie that night and instead they just chatted all night – specifically about things relating to horror and the paranormal.

However she did say that she came out of the bathroom to find Robbie stripped down to his pants.

‘I was fully clothed, and although we had a little smooch, I’d no intention of taking it any further – and I think when Rob realised that, he was on his way,’ she added.

Elsewhere at the show, Kerry revealed the very cheeky reason why her breast implant was ruptured.

During the night, pal Katie, 47, revealed to the stunned crowd how Kerry had ruptured the stitches around her breast during sex.

As Kerry hid behind a pillow, the former glamour model explained to the audience how her stitches came undone.

She said: ‘What do you think happened to her beautiful new boob job.’

Katie continued: ‘He popped it out of the stitching. So now, where they’re having sex like that, he popped it out and it’s now here…’

Kerry interjected: ‘Hang on, hang on a minute… It was totally worth it.’

The crowd could then be heard erupting into cheers and laughter.

Kerry’s admission comes after she revealed how she would be going under the knife again to fix the rupture.

She had her fourth boob job earlier this year, after complaining she looked like ‘a nine-year-old boy’.

Writing in her weekly new! magazine column, she wrote: ‘So I’ve got told to get the surgery again to fix that, which is a pain – but it is my own fault.

‘The surgery is next month, when the tour is finished, so I can properly rest this time.

‘I’m looking forward to being all recovered.’

Kerry had initially planned her boob job after losing weight following her shock split from fiance Ryan Mahoney last year.
