Twilight star Ashley Greene glammed up in a black-and-white Oscar de la Renta dress and a chic sideswept hair, as she attended the Louder Than Words event in Hollywood, California on Wednesday night.

"I'm so proud to be speaking at the @loveisrespect event with@markgirl !" Greene tweeted just before the launch party. "I got to meet some of the youth advisory board members! #inspired."

The gorgeous 24-year old also poses as the cover girl of Lucky Magazine's March issue, styled up in Mulberry top and Dolce&Gabbana mini skirt.

Greene shared stories behind her Hollywood debut and challenges she faced in her Twilight career.

"Twilight has given me something to skyrocket off of. But now that it's ending, there's so much work to be done," said Greene.

"And if I don't do it then Twilight's all I'm ever going to be known for, as great as it is."

What will her post-Twilight career look like?

"Basically I went from 'dying to get a gig' to dying to get the gig everyone wants," Greene told in the interview. "So now I'm in this realm with a lot of highly respected actresses, which is an amazing place to be, but also kind of terrifying." 

In her modeling career too, the Hollywood girl is mercilessly climbing up toward the top of the world. As the latest DKNY ambassador, Greene was featured in Spring 2012 campaign, with photos taken on New York City's rooftops, by photographers Inez van Lemsweerde and Vinoodh Matadin.
