When it comes to date night, expect to find Sara Bareilles and her fiancé, Joe Tippett, checking out a show on Broadway. While speaking to PEOPLE during the opening night of Real Women Have Curves: The Musical at the James Earl Jones Theatre in New York City on Sunday, April 27, the singer-songwriter dished on what a typical evening out looks like for the couple. "Well, we actually do go to a lot of theater," Bareilles, 45, says. "It's one of our favorite things to do." When asked if she had a favorite musical, the performer quipped, "Waitress," before adding that she was "just kidding."
