Advertising Age: Michelle Phan has been the reigning queen of YouTube beauty for years, leading to her own makeup brand via L’Oreal and her own beauty products sample subscription service, among other projects. But in yet another sign that social-media stardom can be short lived, Phan, 28, has been eclipsed not just once but twice by up-and-coming beauty bloggers for monthly views. Bethany Mota, 19, actually surpassed Phan for monthly views for the first time in late 2013 and has kept growing since. An even faster riser, Zoe Sugg, 25, surpassed Phan for monthly views in February, and Mota this spring.
