Kelly Osbourne has vowed to quit posting on microblogging website Twitter.com after an online war-of-words with her ex-boyfriend Luke Worrall.
The pop singer-turned-reality TV star dumped model Worrall in July (10), but admits she is still broken-hearted over their split.
She took to her page on Twitter on Tuesday (28Dec10) to launch a furious rant at Worrall, accusing him of sleeping with dozens of women since the break-up.
Worrall hit back, branding Osbourne's claims "lies" and laughing when a fan congratulated him on his womanising ways - and Osbourne has now decided to quit the website as she is still in turmoil over her ex.
She writes, "Don't 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 (sic) like this in my life."
