Kelly Osbourne has taken a swipe at ex-boyfriend Luke Worrall on social networking site, Twitter. 

Although it's unclear what provoked her series of public messages both to and about him, the singer and face of Material Girl alluded to the fact that he had tweeted about her while she was mourning the loss of Amy Winehouse:

"@luke_worrall you've made it very clear u only dated me 4 my life style but shit 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"

Late last night, Osbourne added "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"
