A representative for teen pop sensation Lorde has denied reports suggesting the singer is engaged after she was spotted wearing a diamond sparkler on her left ring finger.

The Royals hitmaker, 17, sparked rumours she was ready to take her relationship with boyfriend James Lowe, 24, to the next level by stepping out with the eye-catching ring in Houston, Texas on Thursday (06Mar14), but her spokesperson has since brushed off the gossip.

The rep tells Eonline.com, "I can confirm Lorde is not engaged."
