So True? So False? Did Leonardo DiCaprio Buy Blake Lively a Car?

Report says Leo shelled out to buy an eco-friendly ride for his Gossip Girl friend, but did he really buy her a car?

Eco-heartthrob Leonardo DiCaprio and Blake Lively have been spotted riding bikes together, but there's a new rumor that Leo has splurged on another earth-friendly mode of transporation for his latest ladylove.

A brand-new car!

According to one report, Leo bought Blake a black Prius for a cool $40,000, because he "was really put off by her driving around in her gas-guzzling Range Rover."

But is this report true or running on fumes? This story is...

So false!

Leo's rep tells E! News that there is no truth to the story. (Maybe he better let Gossip Girl in on this, too!)

Although it'd be great to get a cool new car, Blake and Leo won't be spotted rolling around the Upper East Side together in a eco-friendly car any time soon.

Why? Because Leo just arrived on set in Sydney today to film The Great Gatsby.
