Chanelle Hayes reveals she is expecting a baby boy

Pregnant Chanelle Hayes is expecting a second son.

The Mirror reports that the reality TV star confirmed the happy news, saying: 'I'm so happy I'm having a boy'.

The Big Brother star also spoke about suffering severe morning sickness with her second baby, admitting she had initially put her contrast in pregnancy symptoms down to having a baby girl this time around.

'I was so convinced it was a girl - with my first baby I wasn’t sick at all and because now I’ve been extremely ill I was sure it would be a girl,' she said.

Chanelle, who appeared on the eighth series of Big Brother, originally confirmed the news of her pregnancy to The Sun Online, with a spokesperson telling the paper: 'I'm delighted to confirm that Chanelle Hayes is pregnant with her second child.'

'Although the news came as some surprise, Chanelle, her partner Ryan and son Blakely are incredibly excited to welcome the new arrival later this year.'

Chanelle is already mum to son Blakely, six, from her previous relationship with footballer Matthew Bates, but had spoken out in the past about her fears that her weight could impact her ability struggle to conceive again.

The 29-year-old, who has gone from a size 8 to a size 18 in recent years, explained during an appearance on This Morning that she has concerns about the implications that her size could have on her fertility.

'I want to have more children - not right now obviously because it's basically impossible - but it's something I want,' she told host Phillip Schofield and guest presenter Davina McCall at the time.

'It's absolutely terrifying. I think because I've been so extreme with the way I've been doing things, when I do put weight on, it goes on a lot quicker.'

Chanelle added that she'd been having problems with pain her back and her knee as a result of the fluctuation, saying: ' 'My back's really really bad. When I have been to the doctors they have said it's because of your weight.'

'I really do want to slim down to feel good but also to be healthy.'

'I was happy at 14-16. I'm an 18 now. I'm on Tramadol, all types of painkillers because I'm too heavy for my frame.'

Chanelle and PE teacher Ryan have been together for a year, and in previous interviews Chanelle has said that she could see herself tying the knot.

'Ryan doesn't know it yet but I'm gonna go with a hell to the yes that our relationship is headed to marriage,' she said. 'It's going really well. Blakeley's all for Ryan, he's not interested in me!'
