Khloe Kardashian Reveals the Surprising Beauty Tip She Got from Jennifer Lopez (Exclusive)

The Kardashians may be beauty gurus, but even they sometimes need advice from an ageless wonder like Jennifer Lopez.

Khloe Kardashian sat down with ET's Keltie Knight on Thursday, and the mom-to-be revealed that J.Lo is her beauty holy grail. "If J.Lo can do something, I can do it too. That's good enough for me!" she said.

"I read about her when she gives an interview. I'm like, I gotta read it -- what are her beauty tips?! 'Cause look at that woman," Kardashian added.

So what is the most surprising advice she's received from the ageless Ms. Lopez? To sleep surrounded by pillows in order to avoid pesky neck lines.

"I was always like, 'What the hell are these lines on the side of my neck? I'm too young for this. What is this?' And I was like, 'Are they [from] aging?'" she mused. "Aging [lines are] up and down. When there's lines on the side of your neck, it's from side sleeping."

Even in her sleep, Lopez is ageless! And we can only guess how many more tips the family was able to get out of the Shades of Blue star when she hosted the Kardashian clan for taco night last month.

A big part of Kardashian's show, Revenge Body, is about achieving both inner and outer beauty, a journey she intimately understands.

"It's so funny 'cause revenge, I think, sounds so aggressive. And for me, I never thought of my body as revenge," she explained. "I just did something for myself, but everyone else was like, 'You have this revenge body.' So, I played with it. I was like, OK, cool -- let's run with that."

"I think it's important to show people you can turn your life around," she continued, noting that the hardest part for her is maintaining her new shape. "You can go through hell and high water, but you can still come out and have a beautiful positive happy life."

Revenge Body returns Sunday, Jan. 7, at 10 p.m. ET/PT on E!.

Back in 2015, Kendall and Kylie Jenner revealed the best beauty advice Khloe and their other two big sisters, Kim and Kourtney Kardashian, ever game them. Find out what they told ET in the video below.
