Showing she’s never afraid to flash a bit of flesh, the 20-year-old flaunted her slender figure and ample ᴀssets as she celebrated two decades of being on the earth.

Gigi Hadid’s supermodel sister looked unbelievable in she chain mail silver outfit, one which gleamed in the light as the star waltzed through the crowds.

The Weeknd’s girlfriend put on an eye-popping display as she showed off her busty ʙosoм, tactically placing a silver star on her nipples to slam any possible wardrobe malfunctions.

Bella’s naturally striking features were only emphasised by a warm, glowing layer of make-up, which included a subtle highlighter, bronzer and an orange eye-shadow which complimented her tanned body.

And the star’s never-ending legs were on full display, even revealing a hint of torso as she strutted out with her mum Yolanda and boyfriend.

The gang headed towards Up and Down nightclub in New York for her private birthday bash, where she was later joined by Justin Bieber’s ex Hailey Baldwin to continue the celebrations.

The latest snaps come just over a week after the model posted a shock pH๏τo with an IV drip in her arm.

The model uploaded the pH๏τo to Snapchat – where she lightened the mood with a cartoon thermometer and drawing of a sleepy person.

And while it’s not known exactly what the model is having the IV drip for, it is thought to be treating her Lyme disease.

The star was diagnosed with the disease in 2012 – an illness both her mother Yolanda and brother Anwar Hadid suffer from as well.

Previously, the stunning model gave fans an insight into her “everyday’”struggle with the disease, in a similar sH๏τ which again showed an IV drip connected to her arm.

Last year, in an interview with ES Magazine, Bella admitted overcoming the negatively of her illness to pursue a modelling career – and have a good quality of life.

Speaking about the impact the disease has had on her, the model confessed: “I used to be the last to go home at a party, now I’m the first … You never really see Gisele out or around. She’s kind of untouchable.”

The disease can cause chronic symptoms which includes fatigue, joint pain and cognitive impairment.

Bella added: “It affected my memory so I suddenly wouldn’t remember how to drive to Santa Monica from Malibu where I lived.”
