《Baby I'm Sorry》的詞曲由美國流行歌手艾薇兒·拉維尼（Avril Lavigne）創作，以下是歌曲的詞語：
Baby I'm sorry
I don't know what came over me
I never meant to cause you pain
I was feeling out of control
And I was scared and I lost my mind
I'm sorry that I was so untrue
I didn't think it would hurt you
I thought you were the one for me
Now I see, I was wrong
Baby I'm sorry, I'm sorry, yeah
I should have known better than to doubt you
And now I realize my mistake
I need you to know that I'm sincere
In wanting you back in my life, yeah
And baby, you can always count on me
For being the best that I can be
I'll make it up to you, I promise
'Cause I love you, and I want you back in my life, yeah
Chorus:
Baby I'm sorry, I'm sorry, yeah
I'll make it better, I swear
If you give me another chance, yeah
I'll be a better girl this time around
Verse 2:
I know that I was being childish
And acting like a teenager in love
But now I understand that you meant everything to me
And I don't want to lose you again, yeah
Chorus: (Repeat)
Bridge:
I don't expect you to forgive me right away (right away)
But I want you to know that I'm sincere (I'm sincere)
And if you take some time to think it over (think it over)
I hope that you'll come back to me someday, yeah (Someday)
Chorus: (Repeat with slight variation) (x2)
