The 29-year-old singer has two sons - Zachary, 10, and Leighton, six - from two previous relationships, and says she'd love to have her first child with boyfriend Joe soon.

Addressing rumours of an engagement between Joe - who has 11-year-old son Harry with his former partner Emma Sophocleous - and herself, Stacey said: "I don't know if Joe and I will ever get married. It's not the top of our to-do list. We want to extend our family first. I definitely see myself having more babies, but because we've got three healthy kids between us we wouldn't be upset if we didn't. We've already got a lovely family."

The former 'X Factor' finalist says she's not particularly strict when it comes to her brood, as she loves taking them out for fast food every now and then.

She added: "One day, I'll be like 'We've got everything organic', and the next minute I'm like. 'Let's go to McDonalds!' I change all the time, but then the kids are always changing, and life is always changing."

Stacey rarely loses her temper with her sons, but says she did recently get into an argument with Joe, 36, after he claimed she should throw out her piano because she never plays it.

When asked by Notebook magazine when the last time she lost her temper was, Stacey said: "Joe and I are moving in together and I've got a piano in my house that I never play. He said I should get rid of it, and we had a big argument. That was the last time I lost it. It was such a silly argument, but it means so much to me, even though I haven't played it in 10 years. I'm keeping it!"
