Family Feud! Inside Lisa Marie And Mom Priscilla Presley's Lifelong Strained Relationship

Despite years of tension and a strained relationship, Priscilla Presley is still right by her daughter Lisa Marie's side. As RadarOnline.com has reported, the 73-year-old is coming to the rescue of her and Elvis’ only child, who is locked in a costly custody battle with estranged husband Michael Lockwood over their two kids, and claims to be flat broke.

To help, mama Priscilla is selling her L.A. mansion, putting the property up for $3.6 million to bail Lisa Marie out of debt, sources say.

Elvis and Priscilla's daughter was born February 1, 1968, nine months to the day after their May 1, 1967, wedding. Lisa Marie grew up in the lap of luxury and followed in her dad's footsteps as a singer-songwriter, but her three albums flopped. She’s the sole heir to her father's estate.

As RadarOnline.com readers know, Lisa Marie and Lockwood married in 2006, and two years later, welcomed twin girls, Harper Vivienne Ann and Finley Aaron Love.

But by 2016, the marriage collapsed, triggering a huge and ongoing custody battle that turned bitter when Lisa Marie claimed that she had found hundreds of images and videos of child pornography on her ex-husband's personal computer.

At the time, Lockwood fought back, saying that Lisa Marie’s statement "contains many inaccurate statements, half-truths, and outright falsehoods."

Now, while mother and daughter have had their own share of issues, it seems Priscilla is ready to support her daughter, whatever it takes. Take a look back at Lisa Marie and Priscilla’s unique relationship in this RadarOnline.com gallery.

“Over the years, Priscilla gifted some of her exes with expensive items that either belonged to Elvis or that he’d given to her,” a source told RadarOnline.com at the time. “Now, she’s been contacting them to ask for them back.”

After the shocking discovery on Lockwood’s computer, twins Harper and Finley were put into Priscilla’s care in late 2016.

“It’s still a very family-oriented environment for them,” Priscilla told ET of taking care of Lisa Marie's twins at the time. "They’re great. They’re doing wonderful. They’re living a great life. They see both their parents, and we’ll see what happens.”

“Lisa Marie is just horrible and Priscilla is pissed off at her for doing all this,” a source told RadarOnline.com in 2017, adding that Elvis’ daughter is “such a drama queen.”

“Butt out of my life! She’s my kid and I’ll raise her the way I see fit!” a source overheard Lisa Marie screaming at Priscilla at the time. "You didn’t do such a bang-up job yourself – so stay out of it!”
