Riley Keoughis showing off her family pride.
The 33-year-oldDaisy Jones & the Sixactress and granddaughter ofElvis Presleywas seen wearing a “Graceland” sweatshirt — a nod to her famous family’s estate in Memphis, Tennessee — while out to lunch with husbandBen Smith-Petersenon Tuesday in Calabasas, California.
Keough’s outing comes just over a month after losing her mother Lisa Marie Presley, the late Elvis' only child, whodied unexpectedly on Jan. 12 at age 54.
It also comes after attorneys for Keough’s grandmotherPriscilla Presleyfiled a petition in Los Angeles last monthquestioning the “authenticity and validity"of a 2016 amendment to Lisa Marie’s trust estate. The amendment named Keough as controller of the trust, which includes Elvis' Graceland property and 15% ownership of his estate, sources previously told PEOPLE.

Late last month, attorneys for Priscillafiled a petition in Los Angelesquestioning the “authenticity and validity” of the 2016 amendment due to various factors, including a name misspelling and an inconsistent signature.
“For some reason, Priscilla doesn’t want Riley to act as trustee without her. The 2010 trust permits Priscilla and Riley to act as co-trustees. The 2016 trust permits Riley to act as trustee alone. Priscilla doesn’t like this,“David Esquibias, a Los Angeles-based probate, trusts and estates litigation attorney, told PEOPLE earlier this month.
It remains unclearjust how long the legal battle ahead liesfor the family, though a hearing for the matter is set for April 13, during which any interested party — in this case, likely Keough — can attend.
“Cases like this depend on whether or not other interested parties and family members disagree with Priscilla’s position. If no one objects it can be completed in as little as a few months,“Benny Roshan, also a probate, trusts and estates litigation attorney based in L.A., told PEOPLE.
“If someone objects to her position and takes a contrary position, e.g. that the 2016 amendment is valid, the litigation can drag out for years,” Roshan added.
