The cosy deep blue sweater was embroidered with delicate ornamental metal embellishment, flaunting her growing stomach.

Teaming it with matching skinny jeans, the yummy mummy-to-be ensured top fashion marks. 

And wearing her hair in its trademark choppy bob, she added a touch of blush and dramatic lashes to complete her TV make-up.

Completing her well put-together look, she rocked a red manicure as she chatted easily to her co-stars, including Chris Tarrant. 

The TV star announced her pregnancy in September on Twitter, posting: 'Charlie & I are very happy to confirm that we're expecting a baby in the new year. Feel so lucky that we're about to become parents. Xx.'

Alex's baby news came just before she emotionally revealed on This Morning her fears that she may not be able to get pregnant.

In an interview with Holly Willoughby and Phillip Schofield, the brunette beauty revealed her 'naivety' over the longevity of her own fertility.

Talking about a documentary she filmed on the topic when she was aged 38, she said: 'My mum went through the menopause at 44 and that's six years older than me.

'I wasn't pregnant when I filmed the documentary. I was 38 and it was terrifying. I was naive. I knew age impacts your fertility but I didn't realise to what extent.' 

Alex also said that it was during filming that she first discovered that her mother had early onset menopause.

'Mum and I never talked about it, it never came up. I always wanted a family. Mum never put pressure on me or my sister to have kids.

'She probably thought I didn't need to know it,' she explained. 

Bumping along nicely: The star treated her 34k Instagram followers to a peak of her growing baby bump, with the caption: 'The bump is gathering pace!'

Meanwhile it was announced earlier this week that Robot Wars presenter Angela Scanlon, 32, and Watchdog host Michelle Ackerley will take over from Alex on The One Show's green couch when she goes on maternity leave.

The flame-haired Irish presenter previously enjoyed a stint on the show earlier, with many taking to Twitter to rave about the style maven's presenting skills.

Michelle will appear on Mondays and Tuesdays, with Angela covering Thursdays and Fridays, while they will both alternate on Wednesdays, starting in the new year.
