The 38-year-old mother of three isn't the first famous face to partner with the British fast fashion brand, whose fans include her kid sisters Kylie Jenner and Kim Kardashian . Olivia Culpo recently collaborated on a PLT range of her own, while Sofia Richie unveiled her collection last year. (Yes, that's the same Sofia Richie who also had a fling with Justin Bieber and is said to be dating Kardashian's ex, Scott Disick. All's fair in love and fashion.)
