No wonder Kelly's driving Billy in-Zane

EXCLUSIVE: Model reveals the shocking truth about her boob-flashing, seduction and men...  

BEWARE! Dangerous curves ahead!

Movie hunk Billy Zane isn't the only one who has been seeing a fair bit of stunner Kelly Brook.

The ex-Big Breakfast babe, now a Hollywood star, has confessed her sexiest secret...she drives motorists to distraction by flashing her naked headlamps as she roars past.

And Kelly—snapped licking ice cream with Billy in St Tropez last week—can't resist slipping from gear and baring her rear end either.

She revealed: "When me and my mates are on the motorway, male drivers tend to get lairy and give us friendly abuse.

"We play them at their own game and moon out the window or display our breasts.

"That shuts most men up. Some try to start a competition by flashing back, but we always win!"

That's no surprise, judging by these sexy new pictures of 32EE Kelly.
While she was playing opposite Billy, 38, in the steamy new thriller Three, insiders say the pair got close.

But both stars insist they're no more than just "great friends".

And Kelly, who flew back to Los Angeles on Friday, vows she is STILL with Lock Stock actor boyfriend Jason Statham (below right), who is currently filming in Miami.

Not that she'd be out on a limb if things went pear-shaped.

"The seduction factor came naturally to me," admitted the busty brunette. "I've never had a problem with my sexuality.

"I'm with Jason now but in the past I haven't had trouble seducing."

She added: "I've no problem with flaunting a little flesh. Why not? It's sexy as hell."

Amazingly, at 24 Kelly says she is still growing. "My boobs have got bigger," she confided.

"It's weird. I've no idea how that happened. But I'm not complaining."

Neither are we. Traffic cops might keep an eye out, though...
