What happened to The Boys fame Erin Moriarty? Details explored as the actress talks about her recent diagnosis on social media

Erin Moriarty, who plays Starlight in Amazon Prime Video's popular show The Boys, has shared details about her personal health struggle. In an open letter posted on Instagram on June 13, 2025, she mentioned that she has recently been diagnosed with Graves' disease, an autoimmune disorder.

She emphasized that symptoms of such conditions can be easily overlooked or misattributed to everyday stress. Reflecting on her own experience, Erin Moriarty admitted that she initially "chalked up" her symptoms to "stress and fatigue." It wasn’t until a formal diagnosis that she began receiving treatment, which she said brought immediate relief.

She urged her followers not to dismiss the warning signs:

"Don't 'suck it up' and rise above pain; you have the right to be comfy," she wrote.

Erin Moriarty mentioned in her Instagram post that she was diagnosed with Graves' disease a month prior. She clarified that she was already experiencing symptoms but interpreted them as stress-induced. Although the 30-year-old actress did not specify what symptoms she had, she noted a breakthrough after beginning treatment.

Moriarty elaborated in her post:

"Autoimmune disease manifests differently in everybody/every body. Your experience will be different from mine. My experience will be different from yours. Perhaps greatly, perhaps minutely. "

The caption further read:

"Within 24 hours of beginning treatment, I felt the light coming back on. It’s been increasing in strength ever since. If yours is dimming, even slightly, go get checked."

Raised and born in New York City, Erin started performing at the age of 11 and later moved on to screen jobs in her teenage years. She had early television roles in Law & Order: SVU, Red Widow, and True Detective, but became better known as Hope in Netflix's Jessica Jones in 2015.

Aside from TV, Moriarty has appeared in a range of independent movies including The Kings of Summer and Captain Fantastic. For her performance in Captain Fantastic, she earned her a Screen Actors Guild Award nomination along with the ensemble cast. Moreover, she played the leading role of Annie January/Starlight in The Boys in 2019.

In March 2024, she was added to the cast of the neo-noir thriller Lips Like Sugar, co-starring Woody Harrelson and Owen Wilson.

In early 2024, Moriarty has also spoken about the pressure of public scrutiny and online misogyny, particularly as her appearance became the subject of speculation.

For the unversed, former Fox News host Megyn Kelly claimed that the actress has had "extreme plastic surgery." This happened during a January 17, 2025, episode of The Megyn Kelly Show podcast. As reported by Entertainment Weekly, Moriarty denied the allegations, calling Kelly's remarks "disgustingly false" and an act of "bullying."

She then reportedly took a step back from social media following comments made about her looks, only to return weeks later with a note of gratitude for her fans’ support.
