Emma Watson is not engaged although she was spotted wearing a diamond engagement ring on the red carpet at the premiere of Harry Potter and the Deathly Hallows.

I better change it quick, otherwise in the papers tomorrow, everyone will be saying I'm engaged, she said to MSN.

Watson joked if she were engaged, this would be a lovely ring.

During an interview on Live! with Regis and Kelly Regis Philbin asked her whether she had developed a fondness for either Daniel Radcliffe or Rupert Grint.

A crush? Regis, seriously, you have honestly asked me this every year since I was ten, she quipped.
