Lisa Marie Presley's ex-husband Michael Lockwood has been granted full custody of their twin daughters Harper and Finley, according to reports.
Riley Keough is said to be "furious" by the decision and fears she is "losing" her half sisters to an "outsider".
Her feud with grandmother Priscilla Presley seems to have worsened following the child custody battle, after Priscilla reportedly didn't raise any objections to Michael getting full custody of the 14-year-olds.
