Amelia Gray Hamlin rocks a crop top and miniskirt to sister Delilah Belle's ... trends now

Amelia Gray Hamlin looked every inch the proud sister as she arrived to her sister Delilah Belle's single release party in West Hollywood, California on Friday night.

As she prepared to celebrate the success of her older sibling's debut track, Nothing Lasts Forever, the 21-year-old model beamed on her way into the Hotel Ziggy.

For the occasion, the five-foot-nine beauty, who made her Vogue cover debut earlier this month, bared her toned midriff in a black and white patterned crop top and matching miniskirt. 

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

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

The Real Housewives of Beverly Hills alum, 59, walked into the bash arm-in-arm with her longtime love while rocking a blue and pink gown with beautifully embellished parrots on the bodice and black bucket hat.

Photographer, Maddie Young, who attended the party, shared photos of Delilah inside, as she had a blast dancing, posing for pictures and enjoying a slice of pizza, on her Instagram Story. 

Delilah, who currently boasts 1.9 million followers on Instagram, released her first song on Saint Patrick's Day as well as a sultry music video.

During an interview with Flaunt Magazine last year, she expressed that over the years, 'I’ve learned that music and writing are really my creative outlets, and they’re ways for me to open up about my struggles, and hopefully share with people through music.'

The music artist continued by adding that she has always 'loved singing,' and that, 'I was in choir, musical theater, and doing vocal lessons at a young age. I thought that I was gonna go into R&B, but I think music is a journey and my genre might change in the future.'

Hamlin then opened up about the genre of music she was creating and revealed, 'As of now, we’re going with ‘ethereal pop’—I’ve made that up.'

Delilah then informed the outlet that, 'I’m currently working on an album. I believe you will be hearing a single first, hopefully, at the top of next year.'

Earlier this year in January, the model hinted that she was working hard on new music when she uploaded a photo series that included a snap of herself recording a track inside of a studio.
