The 25-year-old star – who confirmed last week she had ended her engagement with the model amid rumours he had cheated on her – has defended her former lover and urged fans not to think badly of him.
She tweeted: "'Please stop bashing luke i dont hate him so why should you? we are still best-friends just not dating so enough now please thank you! (sic)"
Despite her heartbreak, Kelly says she is trying her best to stay positive and move on with her life.
She added: "Like i have said onwards and upwards from here thank you guys for all your well wishes/support but lets turn this s**t into a diamond!!!!! (sic)"
Despite Kelly's calm words, the presenter – who started dating the 20-year-old model in May 2008 – has previously posted angry tirades about Luke on her twitter page.
After news of their separation became public, she wrote: "Luke Worall makes me sick!"
However she has since revealed that she 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."
