Amelia Gray Hamlin looked like a proud sister as she arrived at her sister Delilah Belle’s single release party in West Hollywood, California on Friday evening.

As she prepared to celebrate the success of her big brother’s debut track Nothing Lasts Forever, the 21-year-old model beamed as she headed to Hotel Ziggy.

Case in point, the five-foot-nine beauty who made her Debut on the cover of Vogue earlier this month bared her toned bottom in a black and white patterned crop top and matching mini skirt.

She completed her chic look with several layers of pearl necklaces, a pair of thigh-high black leather boots and glossy nude lipstick.

Her famous parents Lisa Rinna and Harry Hamlin were also in attendance to support their eldest, 24, as she launches her music career after making her catwalk debut at 17.

The Real Housewives of Beverly Hills alum, 59, stepped out at the party arm-in-arm with her longtime love in a blue and pink dress with a beautifully embellished parrot bodice and a black hat.

Photographer Maddie Young, who attended the party, shared photos of Delilah inside as she danced, posed for pictures and enjoyed a slice of pizza on her Instagram Story.

Delilah, who currently has 1.9 million followers on Instagram, released her first song on St. Patrick’s Day, along with a hot music video.

During the interview with Flaunt magazine last year, she said that over the years, “I’ve learned that music and writing are really my creative outlets, and they’re a way for me to open up about my struggles and hopefully share them with people through music.”

The artist continued, adding that she has always “loved to sing” and that “I was in choir, musical theater and took vocal lessons at a young age. I thought I would go into R&B, but I think music is a journey and my genre may change in the future.”

Hamlin then opened up about the genre of music she’s been making, revealing, “At the moment we’re using ‘ethereal pop’ — I made that up.”

Delilah then told the publication that “I’m currently working on an album. I believe you will hear the first single hopefully early next year.”

Earlier this January, the model hinted that she was hard at work on new music when she uploaded a series of photos of herself recording a track in the studio.

Close family: Her famous parents Lisa Rinna and Harry Hamlin were also in attendance to support their eldest, 24, as she launches her music career after making her catwalk debut at 17.

When talking with Euphoria magazine back in 2021, Hamlin also opened up about her love for music, but how she put her passion on hold to pursue modeling in the fashion industry.

“You know, I’ve always loved to sing, I’ve always sung in school and vocal lessons and drama classes and so on when I was younger. But then, when I got older and started working as a model, I stepped back a little from that,” Delilah admitted.

“I never really felt confident going into the music world because I was just starting to learn about the modeling world,” she said, “already a lot.”

“I think lately I have become more confident in myself and in what I want to do. So I was engaged in music,” said the beauty.

Also earlier in January, the singer opened up about her health issues and chronic illnesses by sharing a photo of her getting a drip.

She wrote, “For the past few years I have been struggling with autoimmune/chronic disease issues that I have silently fought and overcome.” In accordance with Peoplesome health problems include Lyme disease and Epstein-Barr virus, which can cause infectious mononucleosis.

“Undoubtedly, it was difficult not only physically, but also morally. I kind of kept quiet because I don’t want to be put in a “sick” role,” the star continued. “I’ve been through a lot, I’ve overcome a lot, and I know I’m going through it for a reason, and this reason is to share with you what I’ve been through and what I’ve learned.”

She then quoted preacher Joel Osteen: “If you feel the pressure is too much, it’s because you’re stronger than you think,” later adding, “It may seem overwhelming, but the fact that God allowed it means that you can you handle it.’

In particular, Delilah had an accidental overdose in November 2021 when she mixed up a prescription and benadryl. She also revealed she was addicted to Xanax and claimed her psychiatrist prescribed her too much, according to the publication.

At the beginning of last year, in February, the talented beauty informed her followers that she has been sober for six months.
