Priscilla Presley gets 80th birthday tribute from granddaughter Riley Keough

Priscilla Presley rang in her 80th birthday this weekend.

The actress and the ex-wife of the late Elvis Presley celebrated her 80th birthday on Saturday.

The businesswoman also got a loving tribute from her granddaughter Riley Keough on the occasion.

“HBD queen,” Keough, 35, wrote alongside a throwback photo of her grandmother in the 1960s posing in the driver’s seat of a car.

The image, shared by a fan page and reposted by Keough, showed Priscilla dressed in a floral headband in her hair.

Priscilla previously got a Mother's Day tribute from her son Navarone Garibaldi Garcia, 38, whom she welcomed with music producer Marco Garibaldi in 1987.

In the caption of his May 11 Instagram post, he wrote, “Happy Mother’s Day to my whole world. I love you mama.”

On the professional front, Priscilla is working to release a new memoir Softly, As I Leave You: Life After Elvis on September 23.

The book, which is co-written by Mary Jane Ross, is centered on the “deeply personal story” of what Priscilla “lost and what she found” as she discovered who she was apart from her first love, according to a synopsis.

The memoir will also look at how Priscilla reinvented herself after Elvis' death as a single mother raising their "talented" and "often headstrong" daughter Lisa Marie Presley and then raising Garcia.
