The "Legally Blonde" star, who has been open about her MS journey, shared a sweet photo of her and the "Back to the Future" legend on Instagram with a note expressing her immense gratitude for Fox, who was diagnosed with Parkinson's disease in the early '90s.
The actress previously revealed Fox helped guide her through her multiple sclerosis diagnosis, which she announced in October.
"I like this man. @realmikejfox,"she captioned the pic. "I am not alone in feeling this way. Notice our #underdog shirts. He has #misfits while I have on #badnewsbears . We are all a #timecapsule in this photo. #michaeljfox #selmablair #misfits #badnewsbears #80s #90s #2000s my heart."
She then thanked "Ferris Bueller's Day Off" actress Grey for taking the photo. Mind blown? Blair thought you'd be impressed, noting in the caption, "I just blew your minds. Right?"

Back in February, the 46-year-old actress made her first red carpet debut since her diagnosis at the Vanity Fair Oscar party. Following her emotional appearance, Blair spoke to Robin Roberts on "Good Morning America" and recalled how she reached out to Fox after she wasn't "taken seriously by doctors" before her diagnosis.
"I said, 'I don't know who to tell, but I am dropping things. I'm doing strange things,'" she said of an email she sent Fox. "He got in touch with me and we began a conversation. So he really helped me...He gives me hope."
She added, "Plus I was like, 'I have Michael J. Fox's email now. Like, I'm pretty cool. I'm cooler than I thought.'"
The "Cruel Intentions" star also spoke about her experience with the debilitating disease thus far.
"I am doing very well," Blair 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.
