AceShowbiz - Christina Applegate's personal hygiene has been impacted by her battle with multiple sclerosis (MS). The "Dead to Me" star, who is in relapse now, admitted that she smells "so bad" because she can't stand.

The 52-year-old made the honest confession in the Tuesday, April 2, episode of her "MeSsy" podcast, cohosted by Jamie-Lynn Sigler. "I'm gonna be honest with you, I need to buy stock in Cottonelle because I haven't taken a shower in three weeks," she said. "I can't stand in my shower. There's no f**king way."

"I have such a small bench and my a** is so huge these days that I can't sit on it, it's like I slip right off of it," the actress added. "So, I've been Cottonelle-ing my body."

Christina disclosed that she smells "so bad" and it's such an "awful" experience for her. Luckily, she's "always alone so that no one smells me."

Christina only interacts with her 12-year-old daughter, Sadie, whom she shares with husband Martyn LeNoble. "[Sadie's] always like, 'Oh Mama, that's bad.' I make her smell my armpits, just to make her vomit," she explained.

Christina, who was diagnosed with the degenerative neurological condition in 2021, revealed that she's currently experiencing "intense pain" in her legs and is unable to walk to the bathroom without feeling like she's going to fall.

"Insane tingling that just has spurts of tingles that are weird coming from, like, my butt down," she detailed. "I haven't slept for 24 hours because my eye is doing something weird where every time I close my eye to go to sleep my right eye starts to shift."

Claiming that she has "no energy" and her "legs are just done," Christina added, "[I] definitely am going to have to go in and see someone because it's a little scary and freaking me out that my eye is going to burst out of my face or something." She further shared, "I'm a little concerned about that, and my legs have never been this bad, so I don't know what's going on."
