Apple Martin has admitted to having gotten lip filler.

The 21-year-old model - the daughter of Coldplay frontman Chris Martin and actress Gwyneth Paltrow - has addressed speculation surrounding her fuller lips.

Sharing her Stressed Out College Student beauty routine with Vogue, she spilled: "Time to come clean -- I got lip filler one time.

"I just thought it was too big, but everyone seems to think I have crazy lip filler."

Apple added: "I just pout my lips a lot and I put on a lot of lip filler."

She previously revealed she takes fashion inspiration from her mom.

Apple told Vogue magazine: "She's such a badass when it comes to fashion and has just done what she wants and doesn't really care.

"I feel like I'm finally getting to the place where I don't really care what people think. She influenced me."

Meanwhile, the Goop founder revealed she "started saving clothes" for her daughter around 15 or 20 years "before she was born".

Gwyneth explained: "I don't just see a top, I'll see a moment in my life and all the circumstances surrounding it.

"I've always saved everything in hopes that I had a daughter one day who would want to go in there."

Thankfully, the effort and thoughtfulness paid off as Apple loves fashion.

The Iron Man actress added: "Sometimes we just play dress up and she'll put on my Oscar dresses and stuff like that. We have fun down there."

Gwyneth - who also has son Moses, 19, with her ex-husband Chris - is glad her daughter has developed her own style.

She added to the fashion bible: "I've just watched her style develop and evolve, she's got a very strong sense of personal style.

"She knows how much I love her for exactly who she is. The best advice would just be to unabashedly be herself."
