Kendall and Kylie Jenner
Despite their half-sisters’ earlier success, Kendall and Kylie Jenner seem to be dominating the family now. The latter is the world’s youngest self-made billionaire, an achievement her sisters will never be able to compete for.
Of course, while these two might appear to be competing with their siblings, their relationship is far more profound than money. Kendall and Kylie were made bridesmaids at Kim Kardashian’s 2011 wedding to Kris Humphries. The pair did not want to compete with their sister.
