The 7:30 PM So Beautiful benefit evening features Mueller performing on stage alongside 1999 Siddons Society winner Heather Headley (Aida, The Lion King). Also joining them will be 2008 Siddons winner Deanna Dunagan (August: Osage County).

The Siddons Society also announced plans to celebrate the entire Mueller family, all of whom are stage actors. Parents Roger Mueller and Jill Shellabarger will introduce their four children, Jessie and her sister Abby (Kinky Boots on Broadway), as well as brothers Andrew and Matthew, two popular Chicago performers.

The family will join forces for a special performance.

Bill Zwecker hosts the evening that will include appearances and performances from additional Chicago theatre artists.

All proceeds support the Sarah Siddons Society's Scholarship Fund for theatre students at Columbia College of Chicago, DePaul University, Northwestern University and Roosevelt University. For tickets, visit Beautiful.BrownPaperTickets.com.
