It seems like just yesterday Rachel Potter was making us cry in her moving performance as the Mistress in Broadway’s Evita, and now she’s rocking out onstage every week on the TV competition series The X Factor (and did we mention she’s absolutely killing it?!). This week, Potter brings the ‘80s rock edge in a passionate rendition of Heart’s “Alone,” and the judges (well, everyone but Simon Cowell, but we think he's just jealous) went absolutely wild for her performance. Click below to judge for yourself, then tune in on FOX to see if she makes the cut!
