Kate Moss has been papped with a huge antique sparkler on her ring finger sparking rumours she and her Babyshambles on-off bloke Pete Doherty are engaged.

The model visited Pete backstage on Friday night (August 11) as he recorded a set for Channel 4 music show Transmission (and promptly trashed the stage in true rock star fashion afterwards!)

The pixie-faced couple then carried on partying into the weekend which is when paps captured the shot of Kates huge new piece of finger furniture.

Petes spokesperson didn't deny or confirm the story while Kates agent was unavailable for comment.
