Selma Blair’s sweet message of support for Christina Applegate

Christina Applegate starred together in a 2002 hit film - almost 20 years later, both actresses are battling multiple sclerosis.

Friendship can be ‘The Sweetest Thing’.

Selma Blair wants her friend Christina Applegate to know she’s there for her following Applegate’s multiple sclerosis diagnosis.

“Loving you always,” Blair, 49, tweeted to Applegate on Wednesday. “Always here. As are our kids. Beating us up with love.”

“I love our two weirdos,” Applegate, also 49, responded. “They are so fun.”

The pair’s children are the same age.

Applegate is mum to daughter Sadie Grace LeNoble, who turned 10 on January 27, with musician Martyn LeNoble. Blair welcomed son Arthur Saint Bleick with her now-ex, fashion designer Jason Bleick, on July 25, 2011.

On Tuesday, Applegate shocked fans, revealing her MS diagnosis, saying she received the news “a few months ago”.

“It’s been a tough road. But as we all know, the road keeps going. Unless some a**hole blocks it,” she wrote.

It’s the latest in a string of health trials for Bad Moms star Applegate, who underwent a double mastectomy in 2008 as part of her battle with breast cancer, and had her ovaries and fallopian tubes removed in 2017 to avoid ovarian cancer.

She said in 2019 that she wrote a double mastectomy into her Dead Like Me character Jen’s story.

“It hasn’t really been discussed on shows before,” she said. “I don’t think there’s a lot of characters out there with double mastectomies.”

Blair revealed in 2018 that she had been diagnosed with MS.

The actress, who starred alongside Applegate in the raunchy 2002 comedy The Sweetest Thing, has been open about battling the auto-immune disease, telling fans she felt “sick as hell” in 2019 but vowing, “I am going to get through this. We do. This will pass.”
