TWILIGHT star Ashley Greene insists she is not romancing rumoured boyfriend Adrien Grenier - they share a love of environmental issues.
The actress has been linked to the Entourage star since they were spotted together at a recent charity surfing event.
And Greene is adamant the pair's chat was far from romantic - insisting they talked about their eco-friendly interests.
She tells, "I have only met him once. But he's very smart. We actually started talking about environmental stuff. He's a very go-green guy. I think he's a really sweet guy."
