Jenner hit the milestone in early December and her numbers have likely only continued to grow. No doubt her followers are waiting for any glimpse of a potential baby bump, as the makeup mogul is rumored to be pregnant with her first child.
Since rumors about Jenner's pregnancy began to swirl in September, she has only posted new photos of herself from the chest up and has shared a number of older photos, which fans immediately noticed. She's also continued to promote her company, Kylie Cosmetics, and included snaps from various photo shoots.
The 20-year-old celebrated the achievement on Twitter, writing, "100 f---king million on instagram...that's a loooot of people lol. Wow wow."

Jenner is the second member of her family to pass the 100 million mark, as sister Kim Kardashian earned 100 million followers of her own earlier this year. Sister Kendall Jenner is next in line to hit the illustrious mark, as she currently has 85.6 million followers on the platform.
