Louisa Johnson relishes putting Twitter trolls ''in their place''.

The 18-year-old pop star has previously taken to the social media platform to rubbish critics of her boyfriend Daniel Elliott, and has now admitted she enjoys taking the chance to hit back at online bullies.

The 'So Good' hitmaker said: ''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.''

In October, Louisa shared a holiday snap of herself in a white bikini cuddling up to her boyfriend - but the eye-catching image prompted one social media user to reply: '''your boyfriend ain't even coming close to be honest' (sic)''

Louisa wasn't in the mood to accept the criticism, though, and quickly hit back by saying: ''my boyfriend is my boyfriend cuz he aint shallow like u boy bye. (sic)''

Meanwhile, the teen pop star - who won the UK version of 'The X Factor' in 2015 - has also opened up about her relationship with Daniel, who she has been dating for a year.

The couple - who are thought to have started dating during the talent show - are already living together and Louisa revealed things are ''amazing'' between them.

She told Mail Online: ''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.''
