The Call The Shots singer was also quizzed about whether being in a girl band was a catty experience and while she insisted they never physically fought, she hinted things weren't always harmonious.

'When you're part of the group, girls get the bad reputation, boys are just as bad. Boys will want to fight it out', she began.?

Asked whether they had physically fought, Nadine replied: 'No way! No way! That's definitely not in my personality.'

But recalling her days in the girl group - formed on ITV talent show Popstars: The Rivals in 2002 - Nadine explained: 'You're so busy, so young.

'It's so difficult not to be overwhelmed by everything. And everything was going so well. Our first song was Number One for a month.

'The music I just loved, the shows... That kind of over-weighed... everything else wasn't important'.??

Loose Women presenter Nadia Sawahla attempted to dig deeper into the speculation behind the chart-topping five piece's break-up.

The Promise hitmakers embarked on a hiatus in 2009 before reuniting for their Ten: The Hits Tour four years later and subsequently announcing they had disbanded in March 2013.

Nadia asked whether Nadine being the 'real singer' of the band caused tensions, and the blonde beauty looked shocked.?

'I would never say such a thing!', she insisted, hand on heart. Nadia replied, 'I feel like I'm digging a hole.'

Nadine enthused: 'The great thing about a band is that there's so many personalities, someone is always going to be someone's [fan] favourite.'

Not letting the topic drop, Nadia asked whether they were more like colleagues than friends, to which Nadine nodded enthusiastically.

'It's a great thing, you can get along despite meeting on a TV show', she said. 'I'm not even from the same country as them.'

'We're the lucky ones, it worked out really well for us. There's no emotional scars!'??

Nadine previously claimed that bitterness and jealousy over her lead vocals led to fractious relations in Girls Aloud.

The singer, 34, made the barb during a chat with the new unnamed six part girl group, when she asked them if they had been spending a lot of time together.?

Member Lydia Calvin said: 'It's not been easy. It's quite difficult.'

Appearing to refer to her time with the Sound of the Underground hitmakers, Cheryl responded: 'I know that feeling.'?

In a candid interview with The Sun in September Nadine said tensions had surfaced over her abundance of lead vocals, saying: 'It was fine at the start but there’s always politics in any band.?It just happened that I always got more vocals than everybody else, so in terms of people wanting their voice heard, that wasn’t happening.?

'It made people, very bitter. They didn’t like that. It’s so sad for me to have to admit this stuff now because for so long, there’s the band, and you want everybody to think we’re best friends and we have pillow fights and, you know, drink milkshakes.?

'That’s what I wanted it to be. I really, really wanted that to be, but it just wasn’t how it was. We’re all very, very different characters.'

While it didn't appear to matter for the likes of the Spice Girls - who thrived on each girl's individuality - Nadine retains that their differences led to the eventual split in 2013 - a decision made on the final night of their ten year anniversary tour.

Girls Aloud achieved 22 Top 40 singles, six UK tours, five studio albums and gained the Christmas number one spot with their debut track Sound Of The Underground.
