Kelly Osbourne at The UK premiere of ''The Dark Knight' held at the Odeon, Leicester Square. London, England - 21.07.08

The 23-year-old sparked rumours she is to wed model boyfriend Luke Worrell after she was photographed this week (beg21Jul08) sporting a ring on her ring finger.

But Osbourne claims the band is not an engagement ring - and that she "always" wears jewellery on her wedding finger.

She tells WENN, "I always wear rings on this finger. Luke's 18 and I'm 23 - we're not getting married."
