David Faustino, who played Christina Applegate’s brother in “Married… With Children,” revealed the actress still has her signature humor as she battles multiple sclerosis.

“It’s been very hard for her, but she does keep her humor,” Faustino said in a new interview with US Weekly, calling Applegate’s MS diagnosis “a real blow.”

Faustino, 52, said Applegate, 54, has had a “dry, sarcastic sense of humor since the moment I met her,” and despite the serious health battle that left her recently hospitalized, “nothing has changed.”

The “Dead to Me” star is still “extremely sarcastic” and “extremely dry,” Faustino confirmed.

“She gets through this with some humor, and that’s kind of her way that she moves through it,” the voice actor explained, noting he’s been “a support” to Applegate since she announced her diagnosis in June 2021.

Faustino also confirmed he’s in regular contact with the Emmy Award winner.

“I do a lot of visits with her. A lot of texting, a lot of checking in,” he said. “A lot of funny just crap that we talk about. And that’s all I can do, right? Give her my love.”

He added, “We do have deep convos when we sit. But we also keep the laughter [going] as well.”

Applegate and Faustino played siblings Kelly and Bud Bundy, respectively, in “Married… With Children.”

The sitcom, which aired on Fox from 1987 to 1997, also starred Ed O’Neill and Katey Sagal as their parents, Al and Peggy Bundy.

Applegate gave an update on her health in April after she was hospitalized in Los Angeles.

“Thank you for the outpouring of love and well wishes. Health issues are a constant for me, but I’m a strong chick and I’m getting stronger and better every day,” she wrote on Instagram.

“I’m taking a moment to focus on my health, but I’ll be back with more to say soon enough,” the “You With the Sad Eyes” author added.

Applegate’s rep wouldn’t confirm if the actress was hospitalized due to her autoimmune disease.

“I have no comment on whether she is in the hospital or what her medical treatments are,” the rep told Page Six in a statement on April 16. “She’s had a long history of complicated medical conditions that she has been refreshingly open about, as evidenced in her memoir and on her podcast.”

In February, Applegate revealed she’s been confined to her bed due to ongoing pain, but she still tries to take her 15-year-old daughter, Sadie, to school.

“I want to take her; it’s my favorite thing to do. It’s the only time we have together by ourselves,” the “Friends” star explained.

“I tell myself, ‘Just get her there safely and get home so you can get back into bed.’ And that’s what I do,'” she added.
