Elle Fowler (born May 25, 1988) and Blair Fowler (born April 1, 1993) are sisters who posted beauty and style-related tutorials on YouTube as AllThatGlitters21 (Elle) and juicystar07 (Blair). Elle came into the beauty and fashion world during the summer of 2008 and convinced Blair to join her. Their videos of makeup tutorials and clothing hauls quickly garnered a large audience and rose in popularity. As of August 2017, Elle's videos on AllThatGlitters21 have been viewed more than 180 million times, while Blair's channel juicystar07 has received over 270 million views.
Both sisters previously posted vlogs under the monikers EllesGlitterGossip and otherjuicystar07, allowing subscribers to keep track of their daily lives outside of the YouTube community. Their respective second YouTube channels move away from purely beauty and fashion-related videos and branch into other topics such as health & fitness, their daily musings, and other random interests.
