Ashley Greene says it's "very cool" to appear on a giant Billboard for DKNY.

The 'Twilight' actress is the new face of the brand and says it was amazing to see her campaign be unveiled in New York's Times Square yesterday (22.12.11).

She told WWD: "This is very cool. There are a lot of firsts for me here today. It's my first photo op in Times Square, my first time on one of these buses and my first billboard for DKNY Jeans. It's an exciting day.

"The campaign shots turned out great. They're such talented photographers and really captured the essence of New York."

Ashley is also an ambassador for Mark cosmetics and said she's happy that the two brands she works with are so complementary.

She said: "They pair together nicely. They reach the same demographic - young and carefree. And they both provide a positive message of empowerment for women."

The full DKNY advertising campaign featuring Ashley will be out beginning in early January.
