Singer Bobby Brown just recently debuted a song that he wrote for his late ex-wife Whitney Houston. In an emotional performance, he debuted the song titled "Don't Let Me Die,"  on "The Tonight Show With Jay Leno." The song will be featured on his new album which is planned to be released sometime in June.

In the song, which has very heartbreaking lyrics, Brown confesses that he "messed up pretty bad" and begs Houston to not let him die. He also sings, "I didn’t realize that every breath I took was from you ... You were my air...

I guess I messed up pretty bad ... I didn’t know who you were ... I didn’t know what we had. Now I’m stuck living in the past ... trying to get the pieces back ... but I guess now you’re gone." Aww. Keep your head up Bobby!
