Picture this: every night, you step onto the dazzling Broadway stage in New York City to portray the legendary Carole King. Now, imagine doing that while your younger sister Jessie Mueller has already won both a Tony and a Grammy for originating the same role. That’s exactly what Abby Mueller does as the lead in Beautiful: The Carole King Musical. Instead of sibling rivalry, though, there’s nothing but support between these two talented sisters.

When Beautiful premiered in NYC in January 2014, Jessie Mueller stepped into the iconic role of Carole King. She captivated audiences until March 2015, leaving big shoes to fill. Two years later, Abby Mueller not only took over the role on Broadway but also originated it during the U.S. tour. And guess what? There was no tension or competition—just unconditional encouragement from one sister to another. In an exclusive interview with Closer Weekly, Abby opened up about how incredibly supportive Jessie has been throughout her journey.
