Twilight beauty Ashley Greene denies dating Adrian Grenier – but admits: “I think he’s a really sweet guy.”

Green and Grenier were linked after being spotted getting cosy at a special surfing event in California and then reportedly going on additional dates.

Asked about looking “cute and cuddly” with Grenier, Greene laughed and would only say: “God, that’s what I keep hearing!”

She insisted that their main connection was in fact bonding over concerns for the environment.

“I have only met him once,” Greene insisted.

“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.”

Greene just finished filming the latest installment of the Twilight saga New Moon and is on a break before the cast reunites to start production on the next movie, Eclipse.

“I feel like I’m never in LA, so … I’m just kind of hanging out, getting my life together,” Greene says, adding that she is enjoying filming the sequels even more.

“I’m a little more comfortable in my skin this go-around,” she says. “The second go-around is nice because I get to enjoy it more and breathe it in.”
