Lisa Rinna 'Cried' Watching Daughter Amelia Walk Jean Paul Gaultier Runway at Paris Fashion Week: 'Dream Come True'

Lisa Rinna is opening up about watching her youngest daughter, Amelia Gray Hamlin, hit the runway during Paris Haute Couture Fashion Week.

In a candid Instagram post shared on Thursday, Jan. 30, the RHOBH star, 61, opened up about seeing her 23-year-old daughter walk the runway at the Jean Paul Gaultier show — and the emotional reaction she had to her strut.

"@ameliagray for @jeanpaulgaultier designed by the genius @ludovicdesaintsernin," she captioned her post, which included video footage of the model heading down the runway on Jan. 29.

Hamlin rocked a sexy, metallic-gray two-piece set that featured long ruffled sleeves, a deep v-neck, and a peplum detail at her waist, with the same detail around the knees of her skin-tight pants. The couture outfit was topped off with a long fabric train hanging from the back of her coat, and Gray's hair and makeup was styled down in a sleek, raw look.

"To see Amelia walk, and own this runway in person, was a dream come true for a Mother to see our youngest child come into her own like this!" the proud mom wrote. "I cried. What an exquisite show! ❤️ 😭😭😭."

Hamlin wasn't the only one stepping out in style on Wednesday. Mom-of-two Rinna sported her own sexy two-piece set, rocking a white, oversize pinstripe suit without a top underneath.

The actress' look featured details like visible stitching along her shoulders and at her hips, and she added some flair to the stylish look with a blonde, teased Marilyn Monroe-esque curly hairstyle and peep-toe white heels.

Rinna has been candid about her support for Gray's career as a model (and her older daughter Delilah's work as both a model and actress). Just this month, she spoke to PEOPLE about each of their personal styles, giving them high compliments.

“They have really great style,” Rinna said of her daughter, speaking to PEOPLE at the WWD Style Awards in Los Angeles on Jan. 3. “Come on, look at them. ... I watch everything that they do.”

The star also recalled a recent fitting she attended with her daughters: "I was literally wearing baggy jeans, a tank top and a bomber jacket, and little Mary Janes with socks. I walked in, and they said, 'Oh my God, you look like Amelia.' And I went, 'All right, that’s an amazing compliment.""

Rinna shares her daughters with longtime husband Harry Hamlin — first welcoming Delilah in 1998 not long after the pair tied the knot, and Amelia in 2001.

Amelia made her New York Fashion Week debut in September 2017 when she walked in the Dennis Basso show and has also appeared in a number of magazine photo shoots, including a May 2021 shoot for Paper magazine in which she channeled her mom by wearing the actress's wedding dress.

Additionally, Amelia and Rinna's careers crossed paths when the former reality star walked the Rotate runway during Copenhagen Fashion Week in February 2023.

"I think it's been so beautiful for the two of us to be able to go on this fashion journey together," Amelia told PEOPLE at the time. "Never in a million years did I think that my dreams would also overlap with my mom's, but we're loving this for her. She’s the reason I am who I am. I am so lucky that that is the woman that raised me."
