"Tulisa Contostavlos and Lord Sugar engaged in another Twitter battle last night (November 24). After watching Saturday&amp;#039;s edition of The X Factor, Sugar asked Simon Cowell to fire the &amp;#039;Young&amp;#039; singer. The Apprentice star tweeted: &amp;quot;Get back here and do X Factor yourself and chuck Tulisa out. She knows nothing and talks rubbish.&amp;quot;  Contostavlos replied: &amp;quot;u look like an ugly hobbit. Stop tweeting me &amp;amp; go &amp;amp; find some happiness! It&amp;#039;s embarrassing u miserable old man (sic).&amp;quot;   Back in August  the popstar called the British business magnate &amp;quot;a tw*t&amp;quot; after he proclaimed he didn&amp;#039;t know who she was. The argument continued today (November 25) with the 65-year-old tweeting just three hours ago: &amp;quot;Next PR stunt for @officialtulisa &amp;quot;My cat died of exhaustion and heart attack&amp;quot;. SUN headline &amp;#039;Tulisa agonises over her worn out p**sy&amp;#039;&amp;quot;. Contostavlos has pushed back the release of her album The Female Boss to December 3.
