Considering actress Diane Kruger once played Helen in the movie "Troy," making her "the face that launched a thousand ships," it's no real surprise that she was signed to front the campaign for the fragrance aptly named Calvin Klein Beauty.

At an intimate luncheon held at The Four Seasons in Beverly Hills on an unusually rainy Southern California day, Kruger was a breath of fresh air as she chatted candidly with beauty writers about her involvement with Calvin Klein, and much to everyone's zeal, her love of cosmetics.

"It is a little embarrassing because I own a huge amount of makeup," confessed the actress, who wore a simple black sheath dress paired with a vibrant fuchsia cardigan and her blonde locks pulled back in a low chignon. "I see makeup artists on shoots and then I go buy the stuff so I have boxes and boxes of makeup. I get really bored with the same products so I like to have options. I definitely [love] mascara but I also love fake lashes. I'm obsessed with them."

Kruger, who actually enjoys doing her own makeup, even has a secret weapon in her beauty arsenal that is, dare we say, affordable!

"Cover Girl concealer -- it's really good," she says. "A lot of makeup artists use it. The consistency is really good. It's not too dry. It's a stick."

Among her other beauty favorites are Cetaphil, L'Oreal Triple Active Day Cream and Kiehl's toner.

When it comes to fragrance, of course, these days Kruger finds herself spritzing Calvin Klein Beauty, a feminine and sophisticated scent that puts a new twist on the lily, with notes of ambrette seeds, jasmine and cedarwood.

Becoming the face of a perfume was not a task that the German-born starlet took lightly, admitting that it took her some time before she felt confident about signing on with the line.

"Personally, it was a really difficult decision to make to be the face of a perfume because it's different when you put your name to it as a model," she explains. "I did many perfume ads [while modeling]. I thought, I can't do this and then not wear it or pretend like I like it, but I really don't. It's a weird thing. It took many months before this actually happened. They sent me the sample and I lived with it for a while."

It was also important to Kruger that the ads weren't too provocative, something Calvin Klein fragrances have been known for in the past.

"I love Calvin Klein and I knew the advertising was going to be beautiful," she says. "I think with the campaign it was very important to go with what they wanted to do and what I wanted to do. I'm not a model anymore and I have no interest in doing that again. There needed to be an emotion and something that really embodied the essence of that specific perfume. I personally really like the picture and I think they were really accommodating, especially with the portrait. The portrait, to me, I recognize myself but also, something that I like in fashion, there's a classiness, I guess, to it that I really like. I was a little worried that it was going to be too racy or too provocative because that's not really what I'm like, or the kind of clothes I like. I think it all kind of came together."
