Sian Welby has admitted she was scared she would lose her job at This Morning if she told them she was pregnant before she started.
The mother of one, 38, welcomed her daughter Ruby with her fiancé Jake Beckett last June, at a point where her career was also taking off.
And now Sian has confessed she was in fact already 20 weeks pregnant when she began covering as a co-host on This Morning but kept her pregnancy a secret as she felt she had 'something to prove'.
Opening up on the latest episode of Giovanna Fletcher's Happy Mum Happy Baby podcast, Sian explained: 'When you first start a job, you think "nobody knows what I'm actually like, that I'm trustworthy" and you have to prove yourself.
'I felt like I had proven myself, that I can do this and that. When I got that first This Morning cover with Dermot, I knew I was pregnant but I didn't tell anyone.'
The presenter explained that her co-host Dermot O'Leary didn't know and neither did any of the team as at that point she had only told friends and family and was waiting on her 20 week scan.

She continued: 'In the back of my mind I was thinking "if I tell them I'm pregnant, will this put them off getting me in again?" And will they think "Oh she's gonna be off for ages?"'
'I am sure so many women in any job, especially if they are starting a new one they must think "I have just got this new job and I can't tell them that I'm pregnant".
'It's the fear that you're going to be immediately judged or dropped or they'll go "Oh why you didn't tell us because that is really inconvenient for us now."
'You feel like that, you're like this is so natural and normal why and I feeling so bad of it and so bad about it.'
Sian added that while she did struggle to get some trousers on during fittings for the show she managed to conceal her bump with 'quite forgiving' outfits.
Yet a week later it proved more tricky when she was on a photoshoot as she admitted: 'It was stressful because I still hadn't publicly said anything.'
She joked: 'You can't breath in a baby bump! But I tried.'
Meanwhile Sian recently opened up about achieving her career dream as she told MailOnline: 'I have always wanted to be on This Morning, it was a big mission of mine.
She explained: 'I felt like I had proven myself, that I can do this and that. When I got that first This Morning cover with Dermot, I knew I was pregnant but I didn't tell anyone'
The presenter added: 'It's the fear that you're going to be immediately judged or dropped or they'll go "Oh why you didn't tell us because that is really inconvenient for us now"
After shining alongside Dermot in January last year, she's now very much part of the This Morning set-up (pictured with Craig Doyle)
'In my career, I've had reality stars overtake me, and you lose out on opportunities because they're hot right now, or they weren't looking for someone like me with my accent or whatever the thing was, but I had to wait my turn.'
Sian continued: 'I told two female producers on the show that I would do anything.
'I said, send me to Bognor Regis beach at 2am or get me dressed up as a Smurf in the middle of Skegness, I will do it. I just really wanted to work on the show. So, I did everything for them.
'I did live shows in the middle of Warwick, I was doing competitions and stuff online, a Showbiz segment and a bit like everything in life, I stepped in one day for Lisa Snowdon and it proved to them I could do live TV.
'And eventually the big pinch me moment came when they asked me if I would like to cover with Dermot O'Leary.'
After shining alongside Dermot in January last year, she's now very much part of the This Morning set-up alongside Alison Hammond, Rochelle Humes, Craig Doyle, plus main hosts Ben Shephard and her idol growing up, Cat Deeley.
Sian also admitted her work ethic combined with motherhood has put herself on verge of an 'exhaustion breakdown.'
She explained: 'Some days it is overwhelming and hard. I am not a quitter, I'm very motivated and I don't like anyone telling me that I can't do something and yet I have to admit to myself some days that I can't physically do everything.
'There aren't enough hours in the day. It's got to the point where I have to diary in a wee because I haven't factored in a two-minute moment.
'There are days when I have a 4am alarm, go into Capital, run across London to This Morning, then sometimes a junket and then home to do teatime and bath time.
'I want to spend time with Ruby and when she's been ill, I'm up in the night. There are times I have been sucking snot out of her nose at 1am and getting up a 4am for the radio and still having to do my hair and makeup.'
