Brown wowed audience members after stepping into the role of Eva Perón midway through a performance of "Evita" in London's West End on July 24.

Rachel Zegler had to leave her ‘Evita’ performance mid-show due to falling ill on July 24. Thankfully, her understudy, Bella Brown, stepped in.

Zegler, 24, appeared back onstage in London just one night after her mid-show exit. The Golden Globe-winning actress is currently making her London stage debut as Eva Perón in director Jamie Lloyd's stripped-back revival of the Andrew Lloyd Webber classic rock opera.
