Riley Keough is reportedly "deeply upset at how things are unfolding" amid her legal battle with her grandmother Priscilla Presley.
The pair are currently head-to-head in a complex legal battle over Lisa Marie Presley's trust, with Priscilla claiming she has been pushed out due to an amendment.
A source close to Riley has said she doesn't want to have to deal with the "family drama" and hopes everything will soon "work out".
Riley, 33, and Priscilla, 77, are reportedly "no longer speaking" after they began feuding over Lisa Marie's will.
"The family drama is the last thing Riley wants to be dealing with," the source said.
They also noted Riley is "deeply upset at how things are unfolding," but "she hopes to still be a huge part of [her sisters] Harper and Finley's lives."
Lisa Marie Presley's ex-husband Michael Lockwood was recently given full custody of their twin daughters Harper and Finley.
A court hearing at Los Angeles family court last week ended the seven-year child custody battle between Lisa Marie and her ex-husband.
Riley was said to be "furious" by the decision and fears she is "losing" her half sisters to an "outsider".
Despite the family drama, a second source told Entertainment Tonight : "Riley is hopeful everything in her family will work out."
A source previously told the publication it had been a "very tense and heartbreaking few weeks" for Priscilla and Riley as they became locked in a legal battle just days after Lisa Marie's public memorial.
The alleged growing tension between Riley and her grandmother started just four days after the funeral, when Priscilla filed a petition in Los Angeles questioning the "authenticity and validity" of a 2016 amendment to her daughter's will.
Priscilla is asking a judge to set aside a change made to Lisa Marie's trust which eliminates her as a trustee and replaces her with Riley and Benjamin.
The amendment document misspelled Priscilla's name and had a signature that appeared unusual, Priscilla's lawyers argue.
In a filing to the Los Angeles Superior Court, her lawyers said that she only became aware of the "purported 2016 amendment" after Lisa Marie's death.
Priscilla argues that the amendment was never delivered to her during her daughter's lifetime, as required by the will.
Her lawyers also argue that the amendment was neither witnessed nor notarised.
