On Wednesday the supermodel made an appearance on "Good Morning America" to promote her new skincare line "Rhode," where she gave concerned fans an update on Justin's health.

"He's doing really well," Hailey shared. "He is getting better every single day, and, obviously, it was just a very scary and random situation to happen but he's going to be totally OK."

The 25-year-old continued,

The support has been really amazing just from fans, friends, family. Every single person has sent well wishes, advice, recommendations. It's actually been really amazing."

According to the National Organization for Rare Diseases, Ramsay Hunt Syndrome is "a rare neurological disorder characterized by paralysis of the facial nerve (facial palsy) and a rash affecting the ear or mouth."

One estimate says "five out of every 100,000" people will develop RHS in the US. However, many cases may go undiagnosed or even misdiagnosed.

Despite the hardships, Justin shared a heartwarming post to Instagram in support of Hailey's new skincare line which launched today. He wrote in his caption:

PROUD IS AN UNDERSTATEMENT MY BEAUTIFUL GIRL! So many people are going to have beautiful Dewy skin because of your desire to give them access to the best! LOVE YOU SO MUCH"
