Kim Kardashian revealed that her Instagram account is the main way she keeps tabs on her family members when they can't be around one another.

"Being a big sister, I want to know what's going on in [my sisters'] lives," the reality star said of her four sisters - Kourtney, Khloe, Kendall and Kylie.

"I can look on Instagram and be comforted in knowing where Kendall is."

Kendall Jenner, 19, is a model who travels frequently for photo shoots, her latest being a spread in American "Vogue."

In her recent discussion about social media, the "KUWTK" star mentioned that she's not the only one with an active Instagram account, according to Us Weekly.

"My stepdad [Bruce Jenner] has a secret account," she told the Hollywood Reporter.

Kardashian said the 65-year-old former Olympian set up the account "to see what the sisters are doing, too." This must be the modern way to spy on children.

Kim K has 28.4 million Instagram followers, and her photo of her and husband Kanye West on their anniversary received the most likes of any photo posted on IG.

"I don't have help," she said. "No one else runs my social media. It's whatever I feel like posting. From collages and screen grabs and cropping, it's a whole process, and I do it. I also don't do filters. I can't ever figure it out, and I don't like the way they look, so I'd rather not bother."
