Gigi Hadid shares rare update on older sister people had ‘no idea’ existed

The Hadid sisters have shared a sweet update on their older sibling that people had 'no idea' existed.

Now, it's fair to say that the Hadid sisters - being Bella and Gigi - are two of the many it-girls we're seeing all over social media, catwalks, fashion campaigns and just about everywhere else.

The pair, who also have another full sibling, a younger brother named Anwar, are the children of Mohamed and Yolanda Hadid, who were married from 1994 to 2000.

However, the Hadid family tree goes way beyond just those three as Mohamed shares two children with his first wife Mary Butler, whom he parted ways in 1992: Alana and her older sister Marielle.

Oh yeah, and there's also Aydan Nix, who is Bella, Gigi and Anwar's younger half-sister, who was revealed just this year from a 'brief romance' between Mohamed and Terri Hatfield Dull after his divorce from Yolanda.

Now, there's been quite a big update in Alana's life following her wedding ceremony in Los Angeles over the weekend (18 October), which saw both Gigi and Bella in attendance.

Yep, after wrapping up their busy modelling schedule in New York City with the Victoria's Secret Fashion Show a few days prior (15 October), the sisters flew out to LA to celebrate their half-sister's big day alongside her now-husband Ross Williams, an Emmy-winning producer.

According to details shared with PEOPLE by the bride's rep, the romantic ceremony took place in the private residence of Mohamed.

Sharing a collection of photos on her Instagram Story, Gigi wrote: "Our sister @lanzybear got married this weekend and it was perfect."

While many may have been able to spot the family resemblance from a mile away, it's clear not everyone has been in the know that the sisters have both two older and one younger half-sister.

Gigi and Bella shared the news of their younger half-sister in a statement to the Daily Mail a few months back (29 May).

The pair revealed that Aydan was born after a 'brief romance' Mohamed had with Terri following his divorce.

Their statement also explained that Aydan was born and raised in Florida, and grew up with 'the man she lovingly knew as her father until his sudden passing when she was 19'.

However, after his death, Aydan took 'a genetic test out of curiosity', which led her to realise her 'biological connection' to the Hadid children.

"We first connected in late 2023, and from that moment on, we’ve embraced Aydan with open arms," the Hadid sisters said.

"She’s spent time with all of us, including our dad, and we’ve cherished this unexpected and beautiful addition to our family," the statement continued. "As siblings, we’ve had many open and loving conversations - with Aydan included - about how to support and protect her."

It concluded: "Aydan and her family value their privacy, and we fully respect that. We kindly ask others to do the same and honor her wish and right to her anonymity as she continues her life as a young woman in New York."
