Lea Michele's Heartbreaking Tribute Song for Cory Monteith

Lea Michele is keeping her love for late boyfriend and fellow "Glee" star Cory Monteith alive, in the form of the moving and emotional tribute song "You're Mine."

The track is a last-minute addition to her debut album, "Louder," and one close to her heart. Michele tweeted:

Monteith died of a drug overdose last July, shocking his friends, family, colleagues, and the world at large.

In the song, Michele plaintively croons, "You're mine, for life/And I'll be by your side/We are entwined/You're mine, for life."

(Coincidentally, Mariah Carey also released a song this week called "You're Mine (Eternal).")

Since Monteith's death, Michele has had to grieve in the spotlight. Luckily, she was able to escape some of the glare with the help of a friend — Kate Hudson. The actress offered her home as a refuge to Michele and her family.

"I'll never really be able to thank her, truly, for what she did for me," the "Glee" star told the New York Daily News.

Since then, the actress has been coping. She touched hearts across the country when she tearfully dedicated her Teen Choice Award to Monteith in August. In October, she led the cast in an emotional tribute episode of "Glee" that featured PSAs warning about the effects of drug abuse.

And as she put the final touches on her album, Michele told former "Glee" co-star Jonathan Groff in Teen Vogue that "the insane love Cory and I had for each other morphed into this strength that I have right now."

"There's just something about knowing he's watching everything I'm doing and feeling like I have to do everything now not just for me but for him."

"You're Mine" Lyrics

You're insecure but I was so sure, but I wanted you
It's so powerful, and little girl, but I wanted you
So I told you so, wanted you to know
We've just one life to live

And I told you all my dreams and fears
And you looked at me and your eyes filled with tears
And you said those three words, I've been waiting for
You became a part of me

You're mine, for life
And I'll be by your side
We are entwined
You're mine, for life
Hold me until we go, oh yes, and you will love

I'm yours, you're mine
I'm yours, you're mine

I'm so happy you found the place for me, where you wanted me
Somes insecurities, and two happy beings, where you wanted me
Then you told me so, wanted me to know
You let the past go

And I told you all my dreams and fears
And you looked at me and your eyes filled with tears
And you said those three words, I've been waiting for
You became a part of me

You're mine, for life
And I’ll be by your side
We are entwined
You're mine, for life
Hold me until we go, oh yes, and you will love

I'm yours, you're mine
I'm yours, you're mine

I'm yours, you're mine
I'm yours, you're mine
