Delilah Belle Hamlin joins sister Amelia for a birthday dinner at Nobu

They are the daughters of Real Housewife Lisa Rinna and LA Law actor Harry Hamlin.

And Delilah Belle Hamlin and her sister Amelia Gray headed out to celebrate her birthday on Friday night at celeb hotspot Nobu in Malibu.

The model, who recently turned 22, looked impossible chic in a grey trouser suit as she headed out to celebrate with her sister and a group of pals.

Delilah, who is dating Love Island star Eyal Booker, rocked a plunging satin jacket teamed with a pair of cigarette trousers which highlighted her lithe pins.

She added inches to her height with a pair of slip on white leather kitten heels and accessorised with a chunky hold chain necklace and statement earrings.

The Instagram star swept her brunette locks back into a sleek bun and highlighted her striking features with a pallet of dewy bronze make-up. 

Meanwhile, Amelia, 18, looked stunning in a silk ivory crop top teamed with a ruched maxi skirt, which flashed her gym-honed midriff.

She styled her look with a pair of chunky black boots and a leather satchel bag, while also opting for a full face of make-up.

The sisters playfully posed for pictures outside the restaurant before heading inside to join their friends.

The close pair, who are models, recently signed with the agency UTA and its influencer management company Digital Brand Architects in February this year.  

Amelia had her runway debut in 2017 walking in shows for Dennis Basso and Dolce & Gabbana, while Delilah also walked in Dolce & Gabbana’s Fall 2017 Milan FW show.

Danielle has appeared on the cover of Vogue Japan, while Amelia is the face for Too Faced’s Damn Girl cosmetic line.

The girls are active on their social media channels regularly jibing with their mom Lisa Rinna for her outlandish behaviour online, although it all appears to be in jest.
