Speaking to MailOnline about living with her boyfriend, who she is believed to have started dating during The X Factor 2015 live shows, before discussing the online trolls. 

She said: 'It's going amazing with Daniel, really good. It's been amazing. It's quite normal living with him really, it's just nice to have him around. 

'I think (the trolling is one) of those things. I have that kind of personality where it doesn't really get to me and I tell them to not to do it but I'm one of those people, I can't help myself, I just put people back in their place. 

'Sometimes I want to respond and I know I'm giving them what they want but sometimes I just want to put them back in their place. He doesn't get upset by it, he finds it hilarious.'
