The "Real Housewives of Beverly Hills" star hit the red carpet with her model kiddies Gigi, Bella and Anwar Hadid for the 2015 Global Lyme Alliance Gala in New York City on Thursday.
Foster looked beautiful in her form-fitting midi dress and finished her look with red pumps. The 51-year-old posed with her equally gorgeous children at the event.
Gigi stunned in a strapless white dress, Anwar looked handsome in a classic blazer and white button down, while Bella looked chic in a plunging black midi.
Foster -- who was diagnosed with Lyme disease in 2012 -- also shared some shocking news at the gala. Both Bella, 19, and Anwar, 16, are also battling Lyme disease.
"I honestly don't have the proper words in my vocabulary to describe to you the darkness, the pain, and the unknown hell I've lived these past years," she said during her speech on Thursday. "I actually did not live. I just existed in a jail of my own paralyzed brain. This disease has brought me to my knees. Many nights I wish to die. I pray that I will just wash away into heaven, where there will be no pain."
"God had different plans for me," she explained. "He changed my destiny when my two youngest children, Bella and Anwar, were diagnosed with chronic Lyme disease in early 2012. Watching my babies struggle in silence in order to support me and my journey struck the deepest chord of hopelessness inside of me, and it's because of them that I'm motivated to stand here in front of you today."
"I don't deserve this award," she said, referring to the Power of One trophy she was presented with at the gala. "This award is for Anwar and Bella. This is my token and my promise to you that I will not allow you to live a life of pain and suffering. I will walk to the end of the earth to find a cure so that you can live a healthy life that you deserve. No child should suffer in the way that you do."
