Kelly Osbourne has been snapped strolling through the streets of London with a ring on her engagement finger.

The 23-year-old year-old has made no secret of her love for new boyfriend Luke Worrell and even hinted she wouldn't rule out getting hitched to the model and BMX rider.

She was spotted after a recent trip to New York - where she saw a lot of her 18-year-old lover - looking very glam in a pink dress and matching shoes.

And to complete the outfit, she was wearing a highly visible piece of jewellery on her left hand.

Luckily for the Radio 1 Sunday surgery host, her new beau went down well with the family recently.

She took him out for lunch and shopping with Sharon Osbourne in Los Angeles earlier this month and at one point the former X Factor judge was seen holding Luke's hand.

Kelly still appeared tanned after revealing the new bronzed image in New York, which is a stark contrast to her usual pale look.

She clearly wants to look her best for the man, who may be about to become her husband.

Could Kelly be making wedding arrangements?

Kelly has complained in the past about the difficulty of finding a suitable boyfriend.

She said last month of him : 'We get on so well together. I really do love him.

'Every time we are in each other's company, we always have a good time.'
