The X Factor judge hits back at business guru after he asked what qualifications she had to appear on the show.

Tulisa Contostavlos has hit back at Lord Sugar after The Apprentice star slammed the singer during the showing of The X Factor on Saturday (18^th August) night.

The business star took to his Twitter account to ask his followers what the N-Dubz star "had done" and questioned her position on the music reality series.

He wrote: "Can you tell me who the hell this Tulisa bird is on X factor,she's in the celeb section of the sun and mirror every day. What has she done?" Adding: "This Tulisa talks nonsense on X factor,what qualifications does she have to judge singing talent.Please advise where I am missing the point."

The 'Young' star took to her own social networking account to respond to the remarks and told Sugar he should have "more respect" before listing her musical accomplishments.

"As someone that came from nothing to something maybe u should have a little more respect for people that have done the same," she tweeted. "I have grafted from the age of 11 with my band NDUBZ, we wrote & produced all our music,sold 3 platinum albums,3 sell out tours the last being an arena tour & a number 1 debut solo single!"

She continued: "I have worked my b***dy ass off! So mr lord of judgement… stick to judging on the Apprentice & I'll stick to what I know MUSIC #itsaNOfromme."

The posts have since been deleted and after she commented that the business guru had been "bad mouthing" her for the past year.

Meanwhile, Tulisa is preparing to release her new music video for latest single 'Live It Up' and is expected to release her debut album later this year.
