On Sunday, fans who tried to view Jenner's account found themselves staring at a screen telling them, "Sorry, this page isn't available." But why did she do it?
She may be taking notes from sister Kim Kardashian, who's been extremely quiet on social media since being held at gunpoint and robbed in Paris last month. The entire Kardashian-Jenner crew was likely shaken by the incident, so there's a chance the Vogue cover girl simply decided it was time to scale back her online presence.
There's also a chance that Jenner's decision to get rid of her Instagram account has something to do with her desire to get more involved in standing up for issues she believes in.
In last night's episode of "Keeping Up with The Kardashians," Jenner spoke with sisters Kim and Khloe about doing more to speak out about important issues, like gun violence. The model seemed hesitant to use her public platform to speak about the cause, fearing her celebrity status might "do more harm than good" by taking away from the real message.
The simplest explanation, however, may be that Jenner just decided it was time for a social media break for reasons unrelated to either of the above.
The model spoke about deleting her Instagram account in an interview with Allure published earlier this year.
"I definitely have close friends, and even some family members, who are so connected to their phone and can't get off of it," she said, before recalling a family vacation with sister Kylie.
"It was the first time we had ever been to this beautiful place, and we were sitting in a car," she said. "I was just zoning out, taking it all in. And Kylie wouldn't put her phone down. I'm like, 'That's so crazy to me that you're not experiencing this.' That was the moment it kind of clicked for me. And I didn't like it. So sometimes I delete Instagram or Twitter or Snapchat off my phone for a couple days."
