(Cover) - EN Showbiz - Kelly Osbourne still hasnt got over the heartbreak of splitting from her fianc Luke Worrall, admitting part of her still wants to be with him.

The 25-year-old reality star ended her engagement to the 20-year-old male model in July amid claims he had been unfaithful during their two-year relationship. Kelly was left devastated by the break up as she had been convinced she would spend the rest of her life with Luke.

She says the split was one of the worst things to ever happen to her and she is still coming to terms with the fact that they werent meant to be together.

"It's been the hardest thing I've ever had to deal with in a long time, and I'm not over it," Kelly said during an interview on The Ellen DeGeneres Show. "And for a while I thought... a small part of me wanted to still be with him, but it's not right."

Even though Kelly was madly in love with Luke, she has now accepted he wasnt the right person for her. She claims the spark had gone in their romance before she ended it and she is now trying to move on with her life.

"The best your relationship is ever going to be is how it is when you're dating. We weren't happy anymore, Kelly confessed. I had to go to the next step in my life, and so did he, unfortunately.

It sucked way more because I was going to marry him. I wanted to spend the rest of my life with him, and a part of me still really does, but there is a huge part of me that doesn't."

Kelly says she is now on the lookout for a confident man who is proud to be with her and will always offer her support. (C) Cover Media
