According to the actress, she had to take the image down for copyright reasons. Blair stressed that she didn't remove the photo because she was "embarrassed" by being in a wheelchair.
"So, I posted a picture with Sarah cruising my butt around Disney," she began in the caption. "It resonated with people and was kind of sad about taking down but it was kindly brought to my attention that i don't own the photo and could be sued. And I can't take that hassle. So I took down. Not because I was ashamed or embarrassed, but because it isn't my picture."
Blair went on to thank her friends, including Gellar, for support and expressed gratitude to her "Cruel Intentions" co-star for helping her son have the best spring break ever.
"I am not giving up on having some recovery," she continued in the caption. "Or at least getting stabilized. I am oddly grateful for the new insight I have into a chronically unpredictable body. And I found my friends to be more generous and kinder than I could have imagined... @sarahmgellar @jaime_king @constancezimmer @janeylopatypr @karenzambos and the list goes on and on. This friend, made sure my kid had the best spring break memory with all of us."

Blair concluded by mentioning that she is "grateful" for the mobility aids that are available to help her get around and admitted that although she's in a wheelchair, she hasn't changed as a person.
"And so I am grateful to mobility aids to make it possible. And the best friends to push. And to teach a kid, there is a person In the chair. I am a bit too weak to use my super awesome @the_alinker_world all around with a kid and bad tailbone... and none of this needed an explanation. But I'm a talker ! Hahah. Love . Selma ps. Go #Detroit! And I am in a ....#wheelchair 🤷♀️ still me though."
The 46-year-old actress made her first red carpet debut since her diagnosis at the Vanity Fair Oscar party in February. She looked absolutely stunning at the event and walked with a personalized cane, which she said her manicurist monogrammed.
Following her emotional appearance, Blair's first interview aired on ABC. "The Sweetest Thing" star spoke to Robin Roberts about her experience with the debilitating disease thus far.
"I am doing very well," she said. "I am very happy to see you, being able to just put out what being in the middle of an aggressive form of multiple sclerosis is like. So my speech is -- as you'll notice -- I have spasmodic dysphonia right now."
MS is an unpredictable, often disabling disease of the central nervous system that disrupts the flow of information from the brain to the body, causing problems with vision, balance and muscle control. Spasmodic dysphonia -- a symptom of the chronic disease -- is caused by involuntary movements of one or more muscles of the voice box, otherwise known as the larynx.
