Yet Kylie Jenner couldn't keep it together as she watched her mother Kris Jenner, 64, have her own musical moment as she sang along to Taylor Dayne's 1987 hit Tell It To My Heart.
The 22-year-old cosmetics billionaire and her 35-year-old sister Khloe Kardashian couldn't get enough of the video while taking a break during a poolside getaway on Saturday.
Kylie posted two clips from the video to her Instagram Stories, which showed Kris seated and was dated to July 23, 2018.

The momager had Dayne's dance-oriented hit playing in the background, though it wasn't clear from the audio if she was singing along or just lip syncing, as her voice was most identifiable when she let out a laugh and said: 'Forget it.'
Regardless, Kris was clearly feeling the Grammy-nominated song as she swayed with the beat and had an ecstatic expression on her face.
Kylie and Khloe were obviously tickled by Kris' singing abilities.
'What are you doing mom?!' Khloe exhaled as she broke into a laugh, while Kylie enjoyed it so much that she needed a copy of the video to marvel at later.
'That's amazing, can you airdrop that to me?' she asked.
Both clearly found this side of their mom adorable.
''Mom, you're so cute,' Khloe shouted, and Kylie added, 'You're the cutest person on this planet.'
The Keeping Up With The Kardashians stars appeared to watch the video while on break for a photo shoot.
The two were dressed in bathing suits that flaunted their stunning figures, which Kylie documented in her Insta Stories.
Khloe had on a high-cut white one-piece suit with a plunging top, whereas Kylie wore a brown off-the-shoulder two-piece with straps that wrapped around her upper arms.
The item was made of a textured fabric that made it look like a thick brown bandage wrapped delicately around her body.
Most of the Kardashian–Jenner clan seemed to be gathered together for a relaxing day at the pool.
Kim Kardashian also posted a series of pool photos featuring her younger sister Kendall Jenner, along with Kourtney Kardashian, her former partner Scott Disick and their children.
The kids seemed to have a blast playing in the pool, which prompted Kendall to share a humorous video of herself smiling and giving a big thumbs up while writing, 'still no kids.'
Later, the model showed off her need for speed as she went zooming down a golf course in a golf cart with Kylie in the passenger seat, though she seemed more interested in looking at her bikini in the side mirror than admiring the beautiful scenery.
