The singer revealed her mother Anstey was 'pleased' when she revealed she was a lesbian aged 14.
“To be honest, she wanted to have one of us gay. I know that. She thinks she’s part of the cool club now."
Recalling the moment she told her mum she was gay, she said: "When I came out, it was just like someone had said, ‘I’m nipping to the shops.’ I walked into Mum’s room, she was with my stepdad and I just told her I had a girlfriend - that was it. She was just pleased.
“No way did I think my mum would throw me out after I came out. No one in my family judges anyone like that."
However, Lucy admitted last month that she had not been out to all of her family until recently, revealing her granddad found out she was a lesbian online following her first 'X Factor' audition.
She told Look magazine: "My grandad found out on Google recently and said: 'We’ve got loads of grandchildren, one of them was bound to be gay.'"
She added: "I made my family call me Max when I was four years old and shaved my head to look like a boy. There was no shock."
