London: Singer Britney Spears has slammed reports that she is getting engaged to Jason Trawick.

The 29-year-old pop star sparked engagement rumours after she was spotted wearing a diamond on her left hand but her representatives have denied reports that she is planning to tie the knot for the third time, reported a website.

"The reports are completely untrue. Spears is not heading down the aisle anytime soon. It's not an engagement ring," her representative said.

The hitmaker, who is dating her former agent, for two years, had earlier expressed desire to settle down, saying she was open to a third marriage.

Spears had a 2004 quickie Las Vegas marriage to childhood sweetheart Jason Alexander which annulled after 55 hours. She later went on to marry dancer Kevin Federline with whom she has two children.
