vanity Fair calls these women twilebrities. To be fair they must be saying something worth listening to online to have amassed that number of followers and I am sure that featuring in Vanity Fair will have encouraged more people to follow them.
Though why the mac and the high shoes with the 'suggestion' these women are wearing little underneath?
Is this just a sensationalist story? Were these women selected not for just their number of followers but also for looking great?
Is there an equivalent picture of male twelebrities that you know of?
