"I'd love to have more! I definitely like to have at least one more but yeah you never know what life holds so that's something I'm hoping for in the future," femalefirst.co.uk quoted the 38-year-old singer as saying.
She also said "she loves everything about being a mother but does find it hard to strike the right balance between working and looking after Scarlet."
Though she wants to increase her brood, Melanie says she has been happy with her partner Thomas.
Asked if she had any marriage plans, she said: "Nope, no change there. We're very happy the way that we are. We have talked about it but we're cool, we're happy where we are."
