Riley Keough has taken to social media to write a heartfelt and emotional tribute to her late mother Lisa Marie Presley, who sadly passed away six months ago.

News that the 54-year-old singer-songwriter had died rocked the world, especially given that two days before her passing she was seen at the Golden Globes to support Baz Luhrmann’s blockbuster biopic about her father Elvis Presley, who died when Lisa Marie was just nine years old in 1977.

Austin Butler ended up taking home a Golden Globe for his role in the film on January 10, with Lisa Marie gushing about the young actor on the red carpet and saying that she thought he did a magnificent job in portraying her father and that the movie touched her deeply.

Austin equally returned her admiration, even thanking her in his acceptance speech. “I also want to thank our incredible producers and Warner Bros and the Presley family, thank you guys, thank you for opening your hearts, your memories, your home to me. Lisa Marie, Priscilla, I love you forever,” he said, per the Daily Mail.

However, on January 12, Lisa Marie’s mother Priscilla, 78, took to Twitter to announce that her daughter had been rushed to hospital, writing: “My beloved daughter Lisa Marie was rushed to the hospital. She is now receiving the best care. Please keep her and our family in your prayers. We feel the prayers from around the world, and ask for privacy during this time.”
