The former Spice Girls singer split from the father of her three-year-old daughter Scarlet, Thomas Starr, in July after 10 years together and is worried she has missed her chance to give her daughter a sibling.
The 38-year-old singer told the latest edition of new! magazine: "It would be lovely to havemorechildren but I don`t know if that`s going to happen for me."
Mel C sees Scarlet as her "little buddy" and she loves spending time with her doing girly things like shopping and painting her nails.
She gushed: "She`s amazing. She makes me laugh all day long. She loves singing and dancing and she`s really good at art as well - she loves to paint. She starts school next year so she`s at nursery at the moment.
"She`ll be four in February so she`s at that wonderful age where we have lots of really good chats. It`s lovely to have my little buddy. We go clothes shopping together and I paint her nails."
The brunette star is currently busy touring with musical `Jesus Christ Superstar` and misses Scarlet when she`s away, but they stay in touch via Skype and says she is well looked after by a nanny and her father.
Mel said: "Scarlet sees her daddy a lot as well and I`ve had a nanny since she was seven months old."
