The curious plight of how to eat while wearing lipstick [1] without smudging it everywhere has been mystifying the masses since Lucille Ball jammed something like 20 chocolates into her mouth without a smear in sight. Since then, the number of tips and hacks [2] on the internet has accumulated in spades, but Bella Hadid [3] just let the world in on her own secret. On Wednesday, the model and Dior Beauty ambassador [4] uploaded a video to her Instagram Stories, graciously demonstrating the correct way to eat pizza without fudging up your lipstick [5].

If you haven't seen the clip, fear not. The mini tutorial can be broken down into four cardinal steps:

1. Pick a bright lipstick that's somehow glossy yet long-wearing. While Hadid's makeup artist Peter Philips [6] has yet to share the winning formula, we'd venture to say hers is probably from Dior (the Dior Addict Lacquer Stick in Diabolo [7] ($37) or Dior Addict Lipstick Hydra-Gel Core Mirror Shine in Must Have [8] ($35), perhaps?). Layer if necessary.
2. Break apart bits of a pizza slice into one-inch sizes for easier access to your mouth.
3. Eat said pizza while simultaneously puckering your lips in duck-like fashun.
4. Repeat until fully devoured.
