'I do love going to the theatre and I've seen many West End shows, musicals, all sorts...
'But I do need to apologise to Emma Bunton - who invited me to her Christmas show at the Royal Albert Hall.
'I had a puppy that was six months old and about half an hour into the show...'
But before she could finish her sentence the rest of the panel shouted: 'Half an hour?!'
Kelly continued: 'I got immense anxiety that this little puppy was going to absolutely wreck my house.

Kelly added: 'My mind was somewhere else. I just could not relax.'
Charlene asked: 'So you lasted like three songs?'
'Let's just pretend we're going to the bar,' she explained that she said.
'And we slipped out and we left the show. We left the show, we went home. The puppy was fine.
'It was all in my mind. And from that moment on, in all the time that I've got a dog, I cannot see a show now.'
Judi then asked where her seats were, to which she confessed they were right at the front.
The panel couldn't believe their ears and Charlene asked: 'Do you want to apologise to Emma again?'
Kelly then said to the camera: 'I would love to come back to your show again if you would kindly invite me again.'
She told the panel: 'I know I know it was terrible. But the puppy was six months old!'
