After making her debut through M! Countdown, Lady Jane resumed promoting her debut single on Inkigayo on November 7th after giving Music Bank and Music Core a pass. There's certainly no doubting the talents of Lady Jane, as she was once the vocal for indie band Tiramisu in 2008. Her single album was released last week, and her title song, "Breaking Up Isn't Everything," features her powerful vocals along with a synth pop, modern rock sound. And it wasn't just a simple debut stage for Lady Jane, as her real-life boyfriend, and Supreme Team member, Simon D, appeared during her stage to rap and show us that she is his woman. Check out her sweet debut performance below!
