Former X Factor star Rebecca welcomed daughter Arabella into the world in October, and she also has her hands full with daughter Lillie May and son Karl - not to mention her music career!
During an appearance on This Morning today, Rebecca smiled and said: "I've got three children now - I'm a glutton for punishment!"
Reassuring hosts Eamon Holmes and Ruth Langsford that she was kidding, Rebecca then added: "My family and my kids make me happy.
"It's hard juggling it all, but I've got a great team around me. I've got my mum and my mother-in-law."
Rebecca, who split with Arabella's father before her birth, first revealed she was pregnant in April last year.
The star's announcement came weeks after she fainted during a live performance on ITV1's Loose Women - and Eamon and Ruth were quick to ask her about it.
Recalling that day, Rebecca admitted: "I felt so ill. I felt like I was pregnant, it was gut instinct as I'd been through it before, but I took a test and it was negative.
"I still had symptoms though, so I had to go for all kinds of blood tests. Still nothing showed up."
She added: "Soon after, I was having a cheeky glass of red wine and my gut instinct was telling me no. I took another test and it came back positive!"
Rebecca was on This Morning to chat about her new album, Lady Sings The Blues, which is a tribute to Billie Holiday.
"I've had my ups and downs, but right now I'm in a happy place," Rebecca grinned.
