Lisa Rinna and daughter Delilah Belle Hamlin are looking "more like sisters" than mother and daughter in their latest photo shoot.

Over the weekend, the 58-year-old star took to Instagram to share three photos promoting a new collection from her cosmetic line, Rinna Beauty, co-designed by her eldest daughter.

The mother-daughter duo posed in matching beige outfits, showcasing the brand's Delilah Lip Kit, $63 ($49 USD).

"Nude pink gorgeousness. The Delilah Lip Kit is a MUST HAVE!" Rinna captioned one of the photos for her more than 3 million followers.

The reality star's posts were quickly flooded with comments applauding her latest collaboration, and praising Rinna for looking "barely older" than her 24-year-old daughter.

"Mother-daughter goals," one Instagram user penned, while someone else weighed in, "So beautiful! You look barely older than Delilah, it's wild! Please direct us all to the fountain of youth you've been drinking from."

"You and your daughter are simply gorgeous!" someone else commented.

"You two really look more like sisters! So pretty," one fan sounded off.

"Lisa, you have such a beautiful family! You both look stunning," another added.

One commenter wrote: "Beautiful! Great genes all around!"

"Both your girls are gorgeous, just like mama!" someone else chimed in.

"Daughter is gorgeous — like mother like daughter," wrote another.

Back in 2020, Rinna opened up to Vogue, sharing the secret to her youthful complexion.

“It takes work," she said, adding that "it’s all about maintenance," drinking tons of water and staying active.

"I truly believe it also starts from the inside, so when I've overdone it, or I've had late nights, I've maybe had a few too many cocktails, my skin will show it," she explained before revealing that she starts every morning with a workout class at 8 am. "It's 45 minutes of joy,"
