Rachel Zegler is speaking out.

The actress, 24, has broken her silence after abruptly bringing her “Evita” performance to a grinding halt last week over a mystery illness.

Zegler took to social media Saturday to thank the cast and crew of the London-based theater production after she was wasn’t able to return to the stage for Act 2 on Thursday.

The “Snow White” star shared a photo of herself onstage at the London Palladium on the West End on her Instagram Story.

“Cannot describe the love in this building every night, but today in particular,” Zegler wrote to her 2.5 million followers on the platform.

“I am in awe of this company. The way they come together and never leave anyone behind.”

Zegler praised the cast’s response to her abrupt timeout, saying they “truly hold each other’s hands throughout each number, act and show.”

“The result speaks for itself. Well done swing nation,” she went on, using the industry term for understudies. “Today … my heart literally overflows for you all.”

Bella Brown, Zegler’s understudy, took over during the musical’s second act and performed the production’s signature song, “Don’t Cry for Me Argentina.”

The audience was so pleased with Brown’s performance that they gave the young starlet an almost-five-minute standing ovation.

“Today really showed just how important swings and covers are within this industry,” Brown wrote after the performance. “They are pillars of a show! A proud day to be at ‘Evita.’”

“What a lucky audience getting to see both me and MY ANGEL REG ZEG!”

Zegler stars as the former first lady of Argentina, Eva Perón, in director Jamie Lloyd’s revival of the Andrew Lloyd Webber classic.

The production, which kicked off in June and is scheduled to run through September, marks Zegler’s London stage debut.
