Bitter War: Lisa Marie Presley 'Estranged' From Mom Priscilla For LAST 8 YEARS - OK!

previously reported, Priscilla is currently asking a judge to strike down a newly discovered amendment to Lisa Marie's will nixing her and her daughter's former manager, Barry Siegel, as trustees, and replacing them with Lisa Marie's kids — Riley and Benjamin Keough.

Another pal noted that their relationship had been especially rocky in the days leading up to her death — particularly at the Golden Globes in January, when the pair attended to support Baz Luhrmann's hit flick, Elvis.

The close friend added that the mother-daughter duo were "made to sit together" at the awards show by the Hollywood Foreign Press Association.

As for the cause for the tension in their relationship, the pal confessed the "bone of contention" was that Priscilla and her son, Navarone, often sided with her ex-husband, Michael Lockwood, throughout their messy split.

Despite the legal drama, Priscilla said in a recent statement she is trying to "protect my three grandchildren and keep our family together," during this difficult time.

The sources spoke with New York Post on Lisa Marie and Priscilla's tense relationship.
