Kylie Jenner may have only been a mom for three months, but close family friend La La Anthony, who hung out with the KarJenners at a Business of Fashion dinner Tuesday night in NYC, says the 20-year-old star already has motherhood “down pat.” “She should be giving me mommy advice!” Anthony, who’s mom to 11-year-old son with Carmelo Anthony, Kiyan, told PEOPLE at Thursday’s Arm Hammer event to announce the brand’s new partnership with TerraCycle, which will be re-purposing packaging into new garden planters for the star’s elementary school in Brooklyn.
