The 26-year-old daughter of rocker Ozzie Osbourne and TV personality in her own right took to Twitter to vent about her model ex-fiance Luke Worrall from whom she split in July amid rumors of infidelity.
"He is the worst thing that ever happened to me I don't five a f--- what happens to him anymore," she tweeted to her more than 500,000 followers Tuesday.
She continued: "He used me for my money and a free ride he is lucky I am not spilling the hole [sic] truth about what he did!"
The blonde Brit fired of six angry tweets about her ex beau -- who has been the face of Marc Jacobs and Vivienne Westwood collections -- before vowing to quell her typing tirade.
"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," she tweeted.
The cyber-drama apparently began over Christmas when the British starlet went home to her parents' house: "wow just found something out that has hurt my feeling so bad :( and christmas was going so well [sic]" she tweeted.
The online rant today wasn't the first time Osbourne went online to vent about her ex, whom she was engaged to for 2-1/2 years. During the pair's break-up in July, she posted on Facebook, and later deleted, "Luke Worrall makes me sick!" Us Magazine reported.
