Kendall Jenner’s 67 million Instagram followers discovered Sunday that the model and reality-TV star appears to have closed her account.

As early as 2:58 p.m. that day, fans were asking on the 21-year-old’s still-active Twitter page, “serious question what’s wrong with your Instagram ?! You desactivated ?!”

Jenner’s Facebook page also remains active, though she provides no explanation on either.

Jenner told Allure last month, “I definitely have close friends, and even some family members, who are so connected to their phone and can’t get off of it,” and added that “sometimes I delete Instagram or Twitter or Snapchat off my phone for a couple days.”
