Sarah Michelle Gellar gets emotional as she watches pal Selma Blair do the splits on new DWTS

Selma Blair did a cartwheel and the splits during her inspiring performance with partner Sasha Farber on Monday’s episode of Dancing With The Stars.

And the actress’s best friend and former co-star Sarah Michelle Gellar, 45, got visibly emotional as she watched her performance.

Selma, 50, is battling multiple sclerosis, which affects her balance and motor skills, as well as her memory.

Sarah was seen in tears in the audience as Selma dazzled on the dance floor, doing the splits and cartwheels.

She took to her Instagram story to gush about Selma after her monumental performance with her partner Sasha.

The Buffy the Vampire Slayer star wrote on her Instagram: “I was “All Shook Up” to see my @selmablair live at @dancingwiththestars @sashafarber1 thank you for all the joy and confidence you have shown to Blair.”

Sarah and Selma starred in Cruel Intentions together in 1999.

In August of last year, after receiving stem cell treatment, Blair revealed that she was currently in remission.

MS patients undergoing treatment will go through periods of relapses and remissions.

The actress has faced debilitating symptoms of the disease, including difficulty speaking, and the loss of the ability to use her left leg to its fullest extent, which led her to use a cane to walk.

In her recent documentary about her struggles, Blair said how an MS diagnosis can be “isolating” but was determined to get through it for her son Arthur.

‘I was so burned out. If there was an option to stop me, to regain my balance after being hit so hard with that last flare, it’s definitely for my son. I don’t feel like leaving him now.’

The Cruel Intentions star also praised the tremendous support she received from her friends and family.

“People took very good care of me. I never really like life. I’m doing that now – strange, isn’t it?’ she continued. Just because life is so weird. I was so scared in life. To suddenly find an identity and a safety in me, to discover boundaries, time management and energy. I’m having the time of my life.’
