London, July 23 (IANS) Supermodel Naomi Campbell says Kelly, rocker Ozzy Osbourn's daughter, is free to do what she likes but she should consult her mother before getting engaged.

Kelly, who was photographed wearing a big ring on her finger, has denied that she and her boyfriend Luke Worrell are engaged.

Mirror.co.uk reports that Campbell, who served as guest editor of the site for a day, said she had to put up with the same rumours in the past.

She said: "People are always saying I'm engaged. I've been accused of being engaged 10 times, just because I'm wearing a ring on ring finger. But they are never right. It's up to her if she wants to do it, she's still young. But, personally, I think she should ask her mum first!"
