Project Catwalk presenter spotted wearing ring on her third finger

Kelly Osbourne has sparked speculation she’s planning to marry boyfriend Luke Worrell.

The rock chick was snapped wearing a ring on her engagement finger last night at The Dark Knight premiere in London.

Kelly, 23, has been dating model Luke, 18, since earlier this year.

She had a ‘fake’ wedding 2 years ago to musician Matty Derham. They ‘wed’ at the Electric Picnic festival in Ireland in an inflatable church.
