With more than 5 million subscribers, Brooklyn and Bailey have shown the internet every aspect of their lives. The twins from Lucas, Texas, have uploaded videos about makeup, fashion, boys, their high school drill team, breakups and more. They've launched a scrunchie line and a line of mascara, and fans keep coming back for more. When the twins shared their experience getting their wisdom teeth taken out, the video garnered 21 million views. This fall, they'll take their YouTube channel to Waco when the two attend Baylor University. And we'll keep watching.
