Jun.19 (GMM) Lewis Hamilton on Thursday blankly denied reports he blew nearly $400,000 on a personalised number plate.

Reports earlier this week suggested the 23-year-old McLaren driver is now the owner of the plate 'LEW 1S'.

At a news conference ahead of the French grand prix, Briton Hamilton said the reports were untrue.

"No. Absolutely no interest. That sounds about the worst number plate I've ever heard of.

"I'm not stupid enough to spend a couple of hundred grand on a bloody number plate," he insisted.

"I wouldn't spend a hundred pounds on a number plate. A number plate's a number plate. It doesn't mean nothing to me."
