Katharine McPhee will be making her Broadway debut next month starring in Waitress from April 10 through June 17. The musical features music and lyrics by Sara Bareilles.

Fans first got a taste of Kat’s portrayal of the lead role, Jenna, with a studio recording of “She Used to Be Mine,” which premiered last week.

If that wasn’t enough to have you running to get your tickets to the show, Katharine has been sharing behind-the-scenes videos on her Instagram and Facebook from vocal rehearsals. Check out the video above to hear her sounding phenomenal on a few of the musical’s songs.
