The 26-year-old fashion model from North Carolina, USA, is one of Taylor's closest friends and appeared alongside the musician in her girl power 'Bad Blood' music video.
Speaking in the new issue of Hamptons Magazine about her role models, Martha said: "Definitely my sister, Caroline, because I see her juggle a career and being a mum. And Taylor Swift - I can't say enough good things about her.
"I admire her so much as a person and as a role model for young women. I think we need more people like her; people who want to bring women together and not oversexualize themselves. Plus, she's talented, and she's just the best."
Martha's just one of several models that Taylor counts as close friends: Karlie Kloss, Gigi Hadid, Kendall Jenner, Lily Aldridge and Cara Delevingne are also among her posse.
Chatting to People magazine earlier this month, Martha explained that Taylor had so many friends because she's just such a great person. "She has such an infectious personality. Everyone just wants to be around her at all times. She really brings out the best in everybody."
