She's got less than a month until her due date.

But if Sara Cox could have it her way, she'd be giving birth to baby No.3 sooner rather than later.

Speaking to Chris Moyles today at the end of his show, before she filled in for Fearne Cotton on her morning slot, the 35-year-old revealed she just wants to get on with it.

She said: 'I'm over 36 weeks now so it means it would not be premature any more, so any time is good for me.

'I'm ready now, I'm like bring it on. Let's give birth.'

As she bantered with Moyles, who hosts the breakfast show on Radio 1, she joked: 'It's massive, it's pretty big. It's like I'm hiding the Pennines under here.'

Then, speaking about pregnancy, she added: 'The baby making bit's the fun part. It's the getting it out part that's more challenging.'

After presenting the 10am morning show, Sara was pictured leaving the Radio 1 studios in central London, with her baby bump in tow.

The presenter glowed in a striped top, PVC trousers, knee-high boots and a red scarf.

Despite their hectic schedules, Sara says there’s no big secret to her four-year relationship with advertising executive Ben Cyzer, 32, other than being nice to each other.

The couple are already parents to son Isaac, one, and daughter Lola, four, with her ex-husband.

Speaking recently about getting her figure back once she's given birth, Sara said: 'With my first two I was in maternity jeans for months after.

'The weight doesn’t fall off, I have to work at it. As usual, with this pregnancy I’m all bump and boobs – but I’ve got a muffin top too!'

The DJ, who took six months to return to her usual size 8 to 10 bottom and 10 to 12 top after her previous pregnancies, added: 'It’s important to me to lose my baby weight, I feel much better when I’m slimmer. I’m not in any rush though.'

Matt Edmondson will replace Sara Cox on Radio 1's Sunday Lie In show while she is on maternity leave.

The TV and radio presenter joined the team last month as Fearne Cotton's showbiz and entertainment reporter.
