Taylor Swift says she used to use a Sharpie as eyeliner and we have so many questions

She warned fans not to do it.

Taylor Swift has admitted she used to use permanent marker as eyeliner. Yes, you read that correctly. While her winged eyeliner seems impossibly perfect now, the pop star confessed that she used to "occasionally" draw it on with a Sharpie years ago. The 29-year-old made the odd admission during an interview with Elle for their April issue, where she shared the 30 things she learned before turning 30. She said:

"After my teen years and early twenties of sleeping in my makeup and occasionally using a Sharpie as eyeliner (DO NOT DO IT), I felt like I needed to start being nicer to my skin. "I now moisturize my face every night and put on body lotion after I shower, not just in the winter, but all year round, because, why can’t I be soft during all the seasons?!"

The Look What You Made Me Do singer also reflected on her least favourite beauty look from over the years - that time she bleached her hair right before she played Coachella a few years back. She said:

"Fashion is all about playful experimentation. If you don’t look back at pictures of some of your old looks and cringe, you’re doing it wrong. See: Bleachella."

Elsewhere in the interview, Swift stressed the importance of "learning the difference between lifelong friendships and situationships." She said:

"Something about 'we’re in our young twenties!' hurls people together into groups that can feel like your chosen family. "And maybe they will be for the rest of your life. Or maybe they’ll just be your comrades for an important phase, but not forever. "It’s sad but sometimes when you grow, you outgrow relationships. You may leave behind friendships along the way, but you’ll always keep the memories."
