Pussycat Dolls star Kimberly Wyatt reveals her father Jeff is 'losing the fight' against lung cancer as she admits to feeling 'heavy and hopeless'

Kimberly Wyatt has revealed her father Jeff is 'losing the fight' against lung cancer.

Appearing on Monday's instalment of Lorraine on ITV, the Pussycat Dolls star, 41, admitted to feeling 'heavy and hopeless.'

Kimberly is one of the celebrities to take on a terrifying high-wire challenge in Channel 4's Don't Look Down: Stand Up The Cancer.

The singer told stand-in host Ranvir Singh of her family's sad circumstances as she explained that she was taking part to help raise awareness.

Kimberly said of the challenge: 'If walking a wire can make a difference at all, I'm willing to go out and do it.' 

Kimberly said: 'It's [Cancer] happened all my life. My dad is losing the fight against lung cancer right now.

'You feel heavy, you feel hopeless. If walking a wire can make a difference at all, I'm willing to go out and do it.'

And of walking the high-wire, she added: ''Even in the first experience, it took out fears in me I didn't know were there. Having the mental capability to do jump off a bridge.' 

Love Islander Chris Hughes appeared alongside Kimberly in the Lorraine segment, as he is also taking part in Don't Look Down. 

The reality star said: 'I had a live testicular examination. My cousin had testicular cancer initially, so I went on This Morning and then my brother went to get checked the day after and was diagnosed.

'He says he would never have got checked if he hadn't seen me do it.'

Chris said of the high-wire challenge: 'You're not meant to learn it in 3 weeks. Our instructor said it takes people months. I knew I had a phobia of heights, but I'd only been up a ladder and scaffolding.

'I think my body - the fear just swamped me and I can't help but cry. It gives you a push and reminder why you're doing it. So when I'm bawling my eyes out you know you're doing this to raise money.'

In the challenging series, Paddy McGuinness hosts and leads a team of celebrities as they attempt to work together to tackle an incredible high wire walk.

Set in a summer training camp in the Austrian Alps, over six weeks the famous faces will be coached to conquer their fears as they face a series of physically and mentally demanding training exercises.

Tutored by the world’s foremost experts in high wire walking, at the end of training, the group face the challenge of a lifetime, the most nerve-wracking and vertigo-inducing high wire walk imaginable.

While Paddy will lead the host of celebrities, he will be joined by celebrities including actor Beverley Callard, footballer David Ginola and Love Island star Chris Hughes as they raise funds for Stand Up To Cancer.

Don't Look Down for SU2C continues on Channel 4 at 9.15pm on Tuesday
