Kylie Jenner and Hailey Bieber are girl's girls. Jenner, 28, proved that even though she and Bieber, 28, have their own lip products, they still support each other's beauty empires. In the TikTok video posted on Monday, September 15, the duo beamed at the camera before holding up Bieber's Rhode Peptide Lip Shape and contouring their pouts. After blending the product into their lips with their fingers, the duo switched to Jenner's Kylie Cosmetics Precision Pout Lip Liner.
