This weekend, Tulisa and Alan Sugar had a Twitter spat after he questioned why she deserved to be on The X Factor judging panel
The stubbly entrepreneur told his 2.2million followers: "This Tulisa talks nonsense on X Factor, what qualifications does she have to judge singing talent.Please advise where I am missing the point"
To which Tuilsa curtly replied: "@lord_sugar stick to judging on the Apprentice & I'll stick to what I know MUSIC #itsaNOfromme"
Speaking backstage at V Festival, Tulisa said that she felt obliged to say something because he'd already been slagging her off last year. She also said that he "deserved" to be put in his place.
When questioned about her tough exterior, she said that she feels that she is used to people being mean to her. "It's not that I don't' have feelings, but I'm not going to acknowledge it, because there's nothing positive about acknowledging it or taking it to heart."
She added: "It's not going to change it. So you just put your back up and, whatever. Bring on the abuse!"
What a way to slam the haters, Tulisa!
