She added: "As one of my friends that has MS said 'we wake up and take the indicated action'. And that’s what I do. So now I ask for privacy. As I go through this thing. Thank you xo."
According to the NHS, multiple sclerosis [MS] is a lifelong condition that can affect the brain and spinal cord, causing a wide range of potential symptoms including vision problems, difficulties with arm and leg movement, and balance issues.
Fans rushed to send their well wishes and prayers to the Anchorman star, with one commenting: "Damn! Well let’s face it. You are a true inspiration. Just keep doing what you’re doing. Keep swinging. Keep ducking. You’re a fighter. We’re always rooting for you."
A second wrote: "I'm so sorry to hear this Christina. I wish you all the strength and love to handle and live with this horrible disease."
Christina was also diagnosed with breast cancer in 2008
Others shared their own experiences of living with MS, with one commenting: "I am so sorry to read your news. I have MS too. I'm not gonna lie, it's hard but some days are better than others. Get the right treatment for you, don't be pressured into which meds to have. Do what makes u & Ur body comfortable. You got this, sending lots of love xx."
This isn't the only health battle Christina has faced in recent years. Back in 2008, she was diagnosed with breast cancer and underwent a double mastectomy to remove both of her breasts.
She wrote her cancer battle into her Netflix series Dead to Me, telling USA Today of the decision: "It’s such a personal choice.
"I don’t know what anyone’s going to take away from that moment or scene, except for ‘Wow, I felt that way, too, and I’m going to be OK.’ Because you will. It’s OK to admit that you feel that way."
