TORONTO - Canadian superstar Nelly Furtado is engaged, her friend and music producer Timbaland has told People magazine.

The celebrity magazine reports that the U.S. hitmaker gave a one-word reply when asked if rumours of an impending wedding were true: "Yes."

The Victoria-bred Furtado was spotted brandishing a diamond on her left ring finger at the Concert for Diana in London last week, fuelling speculation that she's planning to get hitched.

The 28-year-old has been linked to Demacio (Demo) Castellon, a sound engineer who worked with Timbaland on Furtado's hit album "Loose."

Furtado, who has a three-year-old daughter, has largely kept her personal life out of the spotlight.

Her publicist has refused to comment on the reports.
