The Saturdays singer and her husband Marvin Humes are expecting their second child together and announced the news last week by posting adorable black and white photos of Rochelle showing off her bump on her social media accounts.

The 'Next Great Magician' host - who already has three-year-old daughter Alaia-Mai with the former JLS star - managed to keep the news she is expecting under wraps until she got to six months but there were times at the start of her pregnancy when she wished people did know because she felt so unwell.

Appearing on 'Loose Women' on Friday (25.11.16), she said: "The first three months I felt horrendous but no one offers you a seat because they don't know, but now I'm six months I feel great."

Speaking about keeping her baby news secret, she added: "It was just super-close people that knew. The first time I found out I was pregnant unfortunately we got papped coming out of a scan which was early on, so I had that taken away from me, so this time I was like, I'm gonna be in control of this and keep it quiet as long as possible.' We did really well, I now know we've got really good friends, because although they love a gossip they actually kept their mouths shut so I'm impressed."

Rochelle, 27, had to go public with her news because she and Marvin, 31, were part of the hosting team for BBC charity telethon 'Children In Need' and her stylist told her that she wouldn't be able to hide her bump on television.

She shared: "I was trying on some dresses with my stylist for 'Children In Need', which was on Friday and I was trying them on that Wednesday or the Tuesday, and he was like, 'Dude I think you're going to have to say something.' "

Rochelle also revealed the stunning photos were taken by a friend of hers at her home and although they were supposed to be a set of shots taken of the pregnant beauty with her daughter Alaia-Mai just for former JLS star Marvin she decided using one of the images would be the perfect way to tell her fans of her happy news.

She said: "They were taken by my friend, she shoots a lot of my stuff, she's an amazing photographer called Paris and she came over to mine and she did that in my lounge. Initially it was to get a picture of me and my little one and the bump for Marvin. I was relaxed because it was in my home, I was telling my little one don't spill the coffee and was chasing after her."
