Although Kelly Osbourne has only been dating Luke Worrall since May, the couple are already engaged to be married. Kelly has been wearing a ring on her wedding finger since September.

Sharon Osbourne, who met Luke during a lunch meeting in July, is said to like him. A friend of the family said:

"Their families were a little concerned at first that they are so young, but they just want to see them happy."

Kelly herself said recently:

"Would I marry him? Yes, you never know. But I’m still really young so we’ll have to wait and see. I really do love him, we get on so well."

On Saturday Luke changed his Facebook status to "engaged to Kelly Osbourne."

Unlike brother Jack, Kelly has always seemed very insecure, and self conscious. She really needs someone to lean on, but if the relationship falls apart she is likely to become a big mess. I’ve got my fingers crossed for Kelly.
