Kelly Osbourne and her ex-fiance Luke Worrall had a very public fight on Twitter yesterday, after Worrall posted a series of tweets insulting Osbourne’s figure.

He made sure he used Osbourne’s Twitter name in the messages so she definitely saw the comments. She was at Amy Winehouse’s funeral at the time.

The DJ and model deleted the tweets after Kelly made a series of cutting replies.

She Tweeted: “@luke_worrall you've made it very clear u only dated me 4 my life style but s*** tweets about me the day im @ a funeral u have hit a new low.

@luke_worrall it was fine when my Kellyphant ass was paying 4everything wasn't it? i just didn't think u could get much lower but u did #wow.”

She added that she was considering quitting the social networking site. "Dont think i want a twitter page anymore the fact that ppl get joy from being mean 2 me makes me sick whats the point? there is to much evil."

Fans responded in support, urging her to block Worrall instead of leaving the site.

The pair split after an eight-month engagement in June 2010, when it was rumoured that Worrall had cheated on her with a pre-op transsexual model.

Last December they had another public fight on Twitter, when Kelly said Worrall was the “worst thing” that ever happened to her.”

He wanted to reconcile and she flew to see him for Christmas in the UK. But she claims that he was using her for money and seeing other women and men behind her back.
