Australian singer Ricki-Lee Coulter is adamant she doesn't want to have children after she marries her fiance.

The 26-year-old star recently announced her engagement to personal trainer Richard Harrison, her partner of three years, but she has now revealed they don't have any plans to start a family.

She tells Australia's New Idea magazine, "I definitely don't have any desire to have children. I feel like I have grown up in a massive family, and I have a little sister who's two and a nephew who's one. I love kids and I'm great with them, but I also love being able to give them back."
