Don't Miss:

Lauren Conrad is a consummate trendsetter, and whether it’s on the streets of Los Angeles or the red carpet, we can’t get enough of her style. Her longtime makeup artist and friend, Amy Nadine gave us the inside scoop on the reality-star-turned-fashion-designer’s must-have makeup and the cool website they created together! “Lauren loves to experiment with her beauty looks, and she’s so fun to be around,” Nadine told us. “When we did a mini-tour of her charity with Mark. cosmetics, we had a blast shopping in Miami, eating and drinking our way through New Orleans and Mississippi, and trying to stay warm in Chicago!” Click through our gallery to get a behind-the-scenes look at what it’s like to work with Conrad!

This weekend, Lauren Conrad Tweeted a picture of her new pink strands—and we got the inside scoop on how she created it! “We used chalk!” her colorist Kristin Ess told us exclusively. “It’s a super-fun way to temporarily color your ends because it washes right out. But it’s best when worn in a bun because it will get on your clothes.” Ess also told us that she and Conrad will be posting a full how-to on their site thebeautydepartment.com tomorrow. And this isn’t the first time Conrad tried color: she previously worked peach tips and blue highlights. (The latter look has been tried on over 100,000 times in our virtual Hollywood Makeover Tool since she got them in September!) Tell us: Do you like her new hue?
