A woman named Mindy McKnight runs a YouTube channel called "Cute Girl Hairstyles" that gives step-by-step instructions for crazy hairdos.
She's racked up more than three million subscribers over the past six years. And now her 14-year-old twin DAUGHTERS are YouTube celebrities too.
They've been in a lot of their mom's videos. But they also have a channel of their own called Brooklyn and Bailey, which recently passed the one-million-subscriber mark.
They post one video a week, and mostly do pointless things for kids to watch. Like their latest video, where they blindfold each other . . . taste stuff . . . and try to guess what it is.
