VIDEO : Kylie Shares Work-Out Selfies 7 Weeks After Giving Birth

After nine months of laying low, Kylie Jenner is back to her old ways -- posting selfies. A month after giving birth to baby Stormi, she has been posting videos to Snapchat of herself working out and showing off her post-baby body. Last week, Jenner uploaded a sponsored ad of herself wearing a waist trainer advertised towards people who want to "snap back" to their pre-pregnancy bodies after giving birth.
