Melanie Chisholm has said her daughter gave her the strength to leave her ex-partner.
The 46-year-old Spice Girl, also known as Sporty Spice, was in a 10-year relationship with property developer Thomas Starr until 2012.
They share a daughter called Scarlett who was born in 2009.
Appearing on Desert Island Discs, Chisholm said becoming a mother had “changed” her.
She added: “She has made me braver. She has made me stand up for myself more.
“I make big decisions. Leaving her dad was hard but I wasn’t happy and she wasn’t happy, and it wasn’t the environment I wanted my child to grow up in.
“I couldn’t have done that without the strength that I got from her.”
