Christina Applegate shared a sweet note of solidarity with the singer: 'From one immunocompromised to another'

While watching Selena Gomez's new documentary My Mind & Me, which details her journey with lupus, Dead to Me star, Christina Applegate -- who in 2021 revealed she was diagnosed with multiple sclerosis -- shared a sweet note of solidarity with the singer.

Taking to Twitter, the actress penned a message for the Only Murders in the Building star. "To @selenagomez Am watching your documentary," Christina's Nov. 7 tweet began. "From one immunocompromised to another. I'm here xo."

The Anchorman actress was also sure to add a bit of levity to her message for the Rare Beauty founder, noting the similarities between their respective autoimmune diseases.

"MS and Lulus are baby sisters from other mothers and a dad who owns a weird truck," Christina added. "Xo. Good on you kid for opening you life to those that need an eye open."

Though it seems that the tweet has been hidden at present.
