Selma Blair broke down in tears on the Vanity Fair Oscars party red carpet while she posed for photos for the first time since announcing her multiple sclerosis (MS) diagnosis.

The actress was showered with support for her brave appearance and penned an emotional Instagram post the following day to describe the moment.

Blair posted a photo of her manager Troy Nankin holding her hand as she walked the red carpet with the help of a cane.

The moment we will all be talking about tomorrow is the courageous #SelmaBlair, making her first appearance since announcing her MS diagnosis, at the VF Oscar party. She needs a cane to help walk, but she came to prove that no matter how tough this disease, she is a fighter. 🙌 pic.twitter.com/bCTo0hA59d

"There are moments that define us. This is one of those indelibly watermarked in my heart. This is #troynankin; my former publicist turned manager, best friend, and fake husband. We joke," she began her post.

"I have become a different woman in the last few years, through struggles and the intense pride of motherhood. @vanityfair has always been a champion of mine, like Troy. And yet, I have not fully realized my capabilities as an actress."

Blair said she was invited to attend the Vanity Fair party and was worried she wouldn't be able to do because she was experiencing a flare-up.

She was grateful to attend, she said.

"And I sobbed. And I appreciated every single second. Every surprising tear, he was there. As he has always been. And that is the reason I could. Thank you Troy. We got me just where I wanted to be. For a night."

Selma said she wanted to make an appearance at the red carpet event to remember the first time she attended the Vanity Fair Oscars party in 2000 with her "not yet famous friend" Jake Gyllenhaal.

"I believed in him and his career and wanted him there," she explained. "And this dinner always symbolizes so much. And I kept going because it was always a night in Hollywood that was full of Hollywood dreams with all the talent present in their glory. I loved to watch."

There are moments that define us. This is one of those indelibly watermarked in my heart. This is #troynankin ; my former publicist turned manager , best friend , and fake husband. We joke. I have become a different woman in the last few years, through struggles and the intense pride of motherhood. @vanityfair has always been a champion of mine, like Troy. And yet, I have not fully realized my capabilities as an actress. I wanted to be at this red carpet to remember my first time attending with a not yet famous friend, @jakegyllenhaal . I believed in him and his career and wanted him there. And this dinner always symbolizes so much. And I kept going because it was always a night in hollywood that was full of hollywood dreams with all the talent present in their glory. I loved to watch. I was invited this year. I am featured in March issue . Thank you @radhikajones @kristasmith @samiranasr #juliemiller @cassblackbird . So this was a streak of light. To say I am here. I am still in an exacerbation so there was some nervousness. I don’t do anything the way I was once able. I will though. I can regain much. Mommas gotta work. And I will be able to do so much more on my own, But this man. Until that comes ...This man and a host of others light the way and hold the moon @thetexastroya was a hero. Wanting me to shine brightly in a time that can be so challenging. He knew I wanted to be able to stand proudly as the woman I have become and hope to be. To be a part of something so special when my body won’t move clearly yet. And then I felt the love from the photographers who have watched me goof around on red carpets since I was in my twenties. I felt the warmth of the bulbs. The strength of my gown. His attentive touch. And still I hoped my brain could send signals for the remainder of my time there. And I sobbed. And I appreciated every single second. Every surprising tear, he was there. As he has always been. And that is the reason I could. Thank you Troy. We got me just where I wanted to be. For a night. And I later pushed my way into a family photo with @dianaross (omg) . So much to post but not before this one. True love. Right here. Forever.
