Sarah Harding had her engagement ring altered because it wasn't "unusual" enough.

The Girls Aloud beauty was stunned when DJ boyfriend Tom Crane proposed to her last New Year's Eve (31.12.10) and though she was delighted by the sapphire-and-diamond piece he popped the question with, the brunette singer recently had the band transformed by British designer Stephen Webster.

Tom said: "I knew Sarah wanted a central sapphire with diamonds but the original ring, although beautiful, wasn't as unusual as she wanted."

Sarah added: "We sent it off to be blinged up - a sort of 'pimp my ring'.

"I wanted something Old School with a modern twist and we knew Stephen was the perfect jeweller to do that. He added more diamonds and changed the shape of the sapphire slightly. The original ring was the perfect foundation - I just wanted it to be more unique."

Tom's decision to propose while the couple were holidaying in the Maldives was sparked by him seeing the original ring in a shop.

He said: "There we were, about to see in a new year in the most romantic place I've ever visited and we spot this beautiful ring. I figured it was fate. I had been thinking about proposing for a while, but I wanted to make sure everything was perfect."
