Yolanda Hadid, 55, flaunts her long legs and toned figure in sexy pre-birthday Instagram

She’s the mom of three top models.

And Yolanda Hadid proved where kids Gigi, Bella, and Anwar got their good looks from as she posted a sexy bathing suit to Instagram Friday.

The Dutch diva, who is 55, showed off her stellar physique wearing a strapless black one-piece that put her fit figure front and center.

Yolanda looked sexy as she showed off her lean legs and toned arms in the pair of photos. Her suit gave the illusion of skin with some crocheted bits over the retired model/author’s center.

Hadid had her blonde hair raked back into a ponytail and glowed with a fresh face. 

Proving she was still hip as can be, she added a pair of trendy oval sunglasses to her look.

‘Celebrating the last day of my 55th year on this planet….. My bestie loves her new iPhone camera and i love the “portrait” setting……….’ she wrote in the caption of her pre-birthday post. 

The post was tagged: ‘#CelebrationOfLife’ and ‘#FreeAtLast.’

Yolanda radiated joy. It seems life is going well for the beauty.

She debuted her relationship with investor boyfriend Joseph Jingoli last August and the pair have been going strong since.

Hadid also recently revealed that her Lyme disease has gone into remission.

In November she told People: ‘I feel better than ever. I’m in remission. I had a really bad year last year but I found a new frequency healing device and it’s been amazing for me. 

‘It took away 90 percent of my symptoms. It helped with my joint pain, the exhaustion, the brain fog, all the symptoms that come with Lyme disease.’ 

Yolanda has been a longtime advocate for those suffering from Lyme, dedicated to promoting awareness and supporting new research.
