Lea Michele has debuted her new single 'Battlefield' which features on her forthcoming album 'Louder'.

The 'Glee' star - who lost her co-star and boyfriend Cory Monteith earlier this year when he passed away following an accidental heroin and alcohol overdose in July at the age of just 31 - released a teaser online of the ballad which tells the story of a lost love and is a follow-up to her first single 'Cannonball' which was released earlier this month.

She sings: ''You and I / We have to let it each other go / We keep holding on but we both know / What seemed like a good idea has turned into a battlefield / Peace will come when one of us puts down the guns / Be strong for both of us /

No please, don't run, don't run / Eye to eye, we face our fears unarmed on the battlefield''

She previously admitted she was scared about releasing her solo album and had concerns about her fans' response after becoming a recognised cover singer in her role as Rachel Berry on the hit show.

Lea said: ''It's really scary because this is all me. What's funny ... I was talking to my mom and she's like, 'This is the opportunity for people to really get to see you, who you are in a personal way.' And I'm excited about that because I've played a character for so long, singing these cover songs, which has been so awesome, and now I'm kind of ready to let people know who Lea Michele really is.''
