Christina Applegate says lying about her breast cancer made her be more honest than ever when she learned she was living with multiple sclerosis over a decade later.

On this weeks episode of the Armchair Expert podcast, Applegate told host Dax Shepard that she allows herself to be angry at MS because of her experience with having cancer and undergoing a double mastectomy in 2008.

This is the worst thing thats happened to me in my entire life, she said of her chronic illness and 2021 diagnosis. I hate it so much and Im so mad about it.

Applegate, 52, said she hasnt always been candid about her feelings regarding her health.

When I had breast cancer at 36 years old, I went out and I was the good girl talking about, Oh, I love my new boobs! ... that are all scarred and fucked up.

What was I thinking? she said.
