The 30-year-old former Girls Aloud star, who is an avid user of the social media, tries to avoid negative comments on her profiles and does not let them get better of her, reported Contactmusic.
"Firstly, I only follow nice, positive people. Secondly, if someone takes the time to follow me and write a horrible comment, I just think, 'Oh, loser, get a life. What are you doing on my feed?' So no, I've learnt not to take any notice," she said.
The 'X Factor' judge also revealed she prefers photo-sharing application Instagram to Twitter these days as her words are often 'twisted', while photos are less easily misconstrued.
