Nicole Richie hosted Urban Decay’s ‘House of Trouble’ event to celebrate the launch of their Troublemaker Mascara. She fronts as the brand’s Troublemaker Mascara campaign and will star in a new video series inspired by her troublemaking ways, launching in early October (Watch Sneak Peak HERE). “I’ve always known I should be a professional troublemaking model, and I’m so grateful that Wende Zomnir and Urban Decay saw my true talent and appreciate my craft,” says Nicole. Beauty and Fashion influencers all gathered to celebrate last night at Hubble Studio with non-stop camera ready activations. Guests were able to take a break from social media by either getting real tattoos or eating some In-N-Out Burger in true troublemaker fashion. Nicole Richie headed out at the end of the evening and was picked up by hubby Joel Madden, while guests received an amazing swag bag filled with Urban Decay goodies.
