Funeral speech reveals Lisa Marie Presley had a secret granddaughter

Lisa Marie Presley was a grandmother and no one knew about it until her funeral over the weekend.

The singer and sole daughter of Elvis Presley tragically passed away on 12 January aged 54 after suffering a cardiac arrest.

Lisa shared Riley and Benjamin with ex-husband Danny Keough and twins Harper and Finley with ex-husband Michael Lockwood.

During Lisa's heartfelt memorial service at Graceland on 22 January, Riley's husband Ben Smith-Petersen read out a letter his wife had written to her late mum.

Within her letter Riley mentioned a daughter, suggesting that, unbeknownst to the public, Lisa Marie had been a grandmother.

"Thank you for showing me that love is the most important things in this life," the letter read.

"I hope I can love my daughter the way you loved me, the way you loved my brother and my sisters."

A representative for Riley Keough has since confirmed to Page Six that she and Ben have a child together, though no further information about the child was offered.

Elsewhere in Riley's tribute to Lisa Marie, she wrote: "Thank you for being my mother in this life.

"I am eternally grateful to have spent 33 years with you. I'm certain I chose the best mother for me in this world and I knew that as far back as I remember you.

"I remember everything. I remember you giving me baths as a baby and I remember you driving me in my car seat listening to Aretha Franklin.

"I remember the way you would cuddle me and when I'd come into your bed at night, and the way you smelled. I remember you taking me for ice cream after school in Florida.

"I remember you singing me and my brother lullabies at night and how you would lay with us until we fell asleep."

Lisa Marie's memorial service also included performances from stars like Alanis Morissette and Axl Rose.

She was laid to rest next to her late son Benjamin.
