And while she was without any sisters,
"My family has experienced a lot of loss in their life and they've been so wonderful in being there for me and giving me the strength I need."
The 27-year-old triple threat will release the first single, Cannonball, off her debut album on December 10–and says the song (which she recorded in August following Cory's death) is:
"…more than just a song to me. It completely helped to lift me up at a time where I needed it. Music can really help you in times of need, and that's what this song did for me and I hope that's what it does for others as well."
Lea also explained how her family got very emotional during the recording of the track:
"I brought my dad to the studio and he cried the entire time. But for me it's been very empowering. I've used this song as a rock."
