Apple Martin is being supremely honest about her past beauty regimen.

The daughter of Gwyneth Paltrow and Coldplay frontman Chris Martin addressed online speculation that she’s gotten lip filler for the first time.

“Time to come clean,” Apple said in the Feb. 12 episode of Vogue‘s Beauty Secrets series. “I got lip filler one time. I think I got it when I was 18. I just thought it was too big.”

“But everyone seems to think that I have crazy lip filler,” she continued, noting that these days, “I just pout my lips a lot and, I put on a lot of lip liner.”

The 21-year-old also walked through her “lip filler optical illusion,” in which she makes her lips look more plump with the help of several products.

“I line right above my lip,” she explained. “Once you get the natural shape of your lips, just go a tiny, tiny bit above it.”

The next key step was to use what Apple deemed “the best lip plumper in the world.”
