The Osbourne family have been joined by celebrity friends as they faced the cameras at a charity gala to raise awareness of Jack's illness.
The 27-year-old reality star was diagnosed with multiple sclerosis last year and he and mum Sharon were given Medals of Hope at the Race to Erase MS event in Los Angeles.
The matriarch walked the red carpet with daughter and Fashion Police star Kelly, while Jack was joined by his wife Lisa Stelly. Dad Ozzy Osbourne - who recently admitted to a drink and drugs relapse - was notably absent from the event.
But the rest of the family were in good company as they were joined by singer Rod Stewart and his wife Penny Lancaster, Spice Girl Melanie Brown, reality star LaToya Jackson and Revenge actor Barry Sloane.
Speaking on the red carpet, Sharon said: "We feel totally spoilt by our friends and family and everybody has been amazing with us. At times like this you realise how lucky you are to be surrounded by so many friends."
Jack revealed how difficult it is to battle the misconceptions about his illness. He said: "When I came out about it in an interview in a magazine the front said 'I will not let my son die'.
"But one per cent of people diagnosed with MS die from symptoms of MS so I thought 'that's right, I'm not going to die because I wasn't going to anyway'.
"Stuff like that has to change on a global level, people have to understand you can live with this and have a high quality of life, people have to wake up to understand what it really is."
Jack said his mum was far more deserving of the gong than himself: "If anyone is deserving it's her because she's been more out front about this than anyone. She's been so supportive - it's nice that it's a family affair."
