British R+B singer Ms Dynamite was a school bully during her adolescence - but she insists her shocking behaviour was due to her low self-esteem.

The IT TAKES MORE hitmaker, real name NIOMI McLEAN-DALEY, is now an anti-bullying campaigner, and admits she deeply regrets her actions.

She recalls, "I put things on to other people by calling them names and intimidating them.

"I didn't realise I was actually bullying them but after I got through that situation in my life, I apologised to them.

"Bullies do it because they feel bad about themselves inside. It's something I regret."
