• We love just about everything about Kate Moss, but we're just not sure how to feel about the latest Moss factoid. Apparently her modeling contract stipulates that she's got to have a cigarette break every 15 minutes ... or else. Says a source who knows about these things: "Kate is actually a dream to work with compared to a lot of high-profile models. But her one major stipulation is that she has extremely regular [cigarette] breaks." Well, we suppose if that's all she's asking, that's not too much. [The Gloss]

• Mary-Kate and Ashley Olsen developed their fashion fixation at a wee age, and on the set of Full House no less. "We'd be in six-hour fittings three times a week, because we had to wear 12 different outfits," Ashley told Net-a-Porter.com's The Edit. Says Mary-Kate: "We were designing clothes for ourselves as we were so petite. So I think that is when we became obsessed with fit, and now the obsession has become a profession." Indeed.

• It may help with cancer, but the latest news? Weed may actually help make you thin. This goes against everything we've ever heard about weed and the munchies. Research from the American Journal of Medicine shows that regular marijuana smokers have a lower BMI than non-pot smokers. Not only that, but they've also got smaller waistlines, lower insulin levels, and lower insulin resistance. So pass the dutchie? [NY Mag]

• Biotherm tapped Leighton Meester as its latest brand ambassador. The former Upper East Sider (that's Blair Waldorf, for you non-Gossip Girl-watchers) was tapped because, says Pattrick Kullenberg, general manager of Biotherm International, "she's a contemporary icon, a young star whose natural talent, energy and beauty have made her the face of a generation." We'll second that. [WWD]

• We love Cara Delevingne because she's forever doing Cara Delevinge-ish things. Like for instance, take what she did last night: Doing whiskey shots and getting a tattoo. This time, the word "silence" scrawled across her wrist. We kind of love it. Cara, and we please hang out? [Styleite]
