The 'Happy' singer, 24, says she would love to become a mother at some point but is too busy concentrating on her career at the moment.
She said: "In the future definitely, but not within five years. I can see myself being an older mother. But I probably haven't given it proper thought as it's so far in the distance. I am a family person. But I say that and I am career driven as well! It's like 50-50."
Leona also admits she gets "angry" when people suggest she should dump her boyfriend Lou Al-Chamaa - who she has known since she was 10 - because she is more successful than him.
She told Britain's Observer Magazine: "It does make me angry. Because he's a great person. And it doesn't matter what you do in life, what your job is, where you come from. None of that matters to me, what matters is who you are as a person - nothing else.
"We are best friends. I feel that all really strong relationships are based on trust. All my friends I've known since I was really little. It's not that I don't let new people in but I do feel safe with people that really know me, who know who I am."
