You may know Aston from JLS as a chart-topping pop star, but did you know he was bullied when he was younger?
He told Newsround his story:
"It all happened when I was 14.
I was in a football team with my friends but then got scouted for a better team. I went there and that's where it started.
I was the only black kid on the team and there was a lot of name calling and verbal abuse.
They were just really nasty to me.
It made me feel really miserable and alone at times. It just wasn't nice.
It made me want to leave the team.
In the end the manager made everybody apologise and I stayed, but that's not to say it didn't affect me."
