Kelly Osbourne has blasted “sl**ty girls” for ruining her relationship

The 25-year-old star – who confirmed last week she had split from fiance Luke Worrall amid rumours he had cheated on her – is trying not to speak badly of her former lover, but is adamant none of her actions were responsible for their separation.

She said: "At first I wanted to tell everyone everything and completely bash him because I'm hurt and angry. But at the end of the day, the truth is I did love Luke and that's all that matters.

"I kept up my side of the bargain and kept my side of the street clean, and no amount of male stupidity and no number of sl**ty girls are going to change that."

Despite her heartbreak, Kelly is trying her best to stay positive and move on with her life.

She wrote in her column for this week's Closer magazine: "Sitting here, bashing him and telling the world how horrible I feel doesn't get either of us anywhere. It's just time to be positive about my new life and to move onwards and upwards."

While Kelly is nursing a broken heart, she knows she will always have the support of her famous parents Ozzy and Sharon Osbourne.

The presenter-and-model speaks to her family every day and they never fail to make her smile.

She told heat magazine: "I call my mum to decide what to wear and she does the same with me. I literally wake up and the first person I talk to is my mum.

"I talk to my dad every day. If he can't get hold of me, he'll call my house and either sing me a song or tell a joke on my voicemail. I keep having to buy a new answering machine because I can't bring myself to get rid of any of them."
