The Saturdays singer-turned-television presenter and her DJ husband Marvin announced via social media that they are expecting a second child.
Marvin told fans: "Absolutely delighted to announce that Rochelle and I are extending our family! We're over the moon! Baby Humes no2 is on the way!"
Rochelle added on Instagram: "Ten tiny fingers, ten tiny toes, but who are you? Nobody knows…."
The couple are already parents to daughter Alaia, three, who they keep out of the spotlight.
Loads of fans and friends have been sending their congratulations, including former X Factor judge Tulisa who tweeted: "Congratulations @RochelleHumes @MarvinHumes on baby number 2!!! Couple Goals
When we spoke to Rochelle in December last year, she told us both she and Marvin hoped to extend their family in the future.
"It's one of those things. When you get married, everybody asks you when you're going to start a family. Then, when your baby is a week old, they ask you when you're going to have your next one," she said,
"I have absolutely no idea. It's not something I plan and I don't know if it will be easy [to conceive]. I also don't know how I would work, be pregnant and juggle a two-year-old. I don't know how I would cope. We definitely want to, but it's not really on the agenda just yet."
And in May 2015, Rochelle told us: "Obviously I want more kids. But at the minute, I'm focused on the one I've got at the moment. I'm quite liking putting all my attention on her. The three of us are having so much fun."
Now that baby number two is on the way, perhaps Rochelle will turn her attention to designing maternity and kidswear?
The popstar already has a range with Very.co.uk, but said last year she'd love to expand it: in the future "Maternity wear, maybe that's what I'll do next but I think I'll have to be pregnant to be in that mind space and that's not going to be for a little while so there'll be no rushing."
Congrats to Rochelle and Marvin!
