London, Dec 30 (IANS) Singer Kelly Osbourne is extremely heartbroken and angry – so much so that she took to micro-blogging site Twitter to vent out her frustration over former fiance Luke Worral’s disloyal ways.

The 26-year-old star launched an angry tirade against Worral, and also said that she would be off social networking for sometime as she needs some space for herself to deal with her feelings, reports femalefirst.co.uk.

‘Dont think I have ever felt so stupid he made a fool of me going to be off Twitter for a while never felt heart brake like this in my life.(sic),’ Osbourne posted.

Osbourne and Worral split in July when rumours were abuzz that he had been cheating on her. But her angry tweets came after she realised that he had been unfaithful multiple times.

‘What do you do when someone lies in the darkest way and you try to tell the person that was lied 2 but they don’t believe you? (sic),’ she wrote.

I am and always will be 2 good 4 @luke_worrall darling ur pretty face will only get you so far because u don’t have the brains to back it up. (sic)’

Worral, who celebrated his 21st birthday Sunday, chose to ignore the messages, but went on to post: ‘Lies on Twitter awesome. (sic)’

On being asked to respond to Osbourne, he said: ‘No because I’m not going to spill personal business over twitter I’m not that low! (sic)’
