In recent weeks, Cheryl has been at the centre of a whirlwind of pregnancy rumours.

So fans are avidly watching her every move, with her latest work role seemingly providing a hint at her rumoured journey to motherhood, as she was named the latest ambassador of Childline.

The 33-year-old songstress - who is said to be expecting with her boyfriend Liam Payne, 23 - was unveiled as the face of the charity in the week of its 30th birthday, and appeared in a harrowing campaign video for it.

Chilling: Cheryl unveiled her role in the new TV campaign for Childline on Wednesday

Cheryl remains coy about her alleged pregnancy despite showing off a rounded stomach and the fabled new mother glow of late.

She confirmed her relationship with One Direction hunk Liam earlier this year shortly after the demise of her short-lived marriage to French businessman Jean-Bernard Fernandez-Versini.

In a chilling Childline video, Cheryl voices the struggles of young people dealing with issues like self-harm and sexual assault.

Eerie: The video is shot in a school hall, where Cheryl sits alone in a chair

Sitting on a chair in the middle of a room, she mouths: 'I've been cutting since I was 13. I'm so tired of it, but I just don't know how to stop.'

As the voice switches to another youngster, she says: 'I'm worried my dad will lose it if I tell him - I'm gay'.

Voicing a young girl, she says: 'I sent this boy pictures because he kept asking and asking me. Now he wants more. If I don't, he'll show everyone.'

One especially harrowing tale continues: 'In the night, when everyone's asleep he comes in and does things to me.'

In the accompanying shoot for her new ambassador role, the former Girls Aloud star was glowing as she posed in a loose-fitting blue T-shirt adorned with the Childline 'C' logo.

Looking preened to perfection, the beautiful singer wore her chestnut tresses in loose waves falling from a centre parting while her make-up was dewy with a slightly smudged brown eye-shadow palette.

When Cheryl filmed the clip back in September, a member of her PR team tweeted a snapshot of the brunette beauty posing for a selfie in between takes.

It was the first time she had been photographed since pregnancy rumours emerged and the image caused uproar due to the fact it was a cropped close-up.

Working on it: Cheryl's partnership with the charity will focus on bringing awareness to teenagers to reach out to the group, set up by Dame Esther Rantzen in 1986

A month later, the mystery project she was working on has now been revealed as her Childline collaboration, which will no doubt be taken as a further maternal hint by her adoring fans.

Cheryl's partnership with the charity will focus on encouraging teenagers to reach out to the group, set up by Dame Esther Rantzen in 1986.

Of her campaign, the Fight For This Love hitmaker said: 'As a teenager I was aware of Childline, but like so many others I mistakenly thought it was just for young kids.

'The reality is that it doesn’t matter whether you are at primary, secondary school or college, or how big or small your problem is, Childline is there for you.

'Life can be hard sometimes, especially whilst you’re growing up, and everyone deserves someone to talk to and help make sense of it all. That is exactly what Childline is there to do; just listen and help.

'No young person should ever feel afraid, confused or alone so if that’s how you are feeling then please get in touch with them by phone or online.'

NSPCC's chief executive officer Peter Wanless said: 'Welcoming Cheryl as the new face of Childline is an absolutely fantastic way for the service to mark 30 years of helping children and young people.

'Through her support we will be able to reach a lot of young people who previously weren’t aware of Childline or perhaps thought that they were either too old or that their problem was not serious enough to warrant seeking help.

'The reality is that Childline is here for every child and young person and there is no better person than Cheryl to help us spread this crucial message.'
