Selena Gomez has become the first woman to have 400M Instagram followers, just weeks after passing Kylie Jenner on the social media platform. Jenner is now second, with 382M followers. In order to take the overall lead, the singer/actress might want to take up soccer: she trails soccer legends Cristiano Ronaldo, who has 562M followers, and Lionel Messi, who has 442M.
