Her mother Yolanda has been battling Lyme disease since 2012.

And daughter Bella Hadid used her GQ Men Of The Year Awards victory on Tuesday night to pay tribute to the Real Housewives of Beverly Hills star, who accompanied her to the London bash.

'This is the first time my mum has been out of bed in four years and got her hair and make up done and I'm so happy she's here', she told the audience, after scooping the Model Of The Year award.

Clearly very nervous, Bella addressed the glittering audience, who included Ellie Goulding, Daisy Lowe, Chris Pine and Ricky Gervais.

'I'm having a heart attack a little bit,' she said. 'This is crazy. I've worked really hard - it's crazy to be recognised.'

Proud Yolanda, 52, looked stunning in a chic one-shouldered jumpsuit with gold zip detail, contrasting with her daughter's off-the-shoulder dusky peach gown.

Lyme disease is an infection caused by bacteria spread by the bite of an infected deer tick.

Symptoms include pain in the muscles or joints, fever, malaise, and chronic fatigue.

No definitive treatment or cure for the illness has been found - and last year Yolanda revealed that Bella and her younger brother Anwar also have the condition.

Yolanda recently underwent surgery in a bid to finally conquer the debilitating disease, having what is known as a Transvascular Autonomic Modulation procedure.

TVAM is a relatively new procedure which has been suggested as a treatment for those suffering Multiple Sclerosis and other autoimmune disorders.

Yolanda recently revealed in a Bravo blog that Bella had to give up her dream of competing in the Olympics due to symptoms of the disease.

'Bella had to give up her lifelong dream of having a professional riding career and a shot at the Olympics due to her severe symptoms and inability to ride,' she wrote.

'This was the biggest heartbreak of her life and an extremely sensitive subject for her. She is resilient and focused on a new direction--she's made a name for herself in the modeling industry while she struggles with symptoms of chronic Lyme every day.'
