Justin Bieber的《Boyfriend》的歌詞如下：
Baby, baby, baby, oh
Boy, you're a fire
And I can't control my urge
To kiss you, kiss you, kiss you
Girl, you're my oxygen
I need you by my side
When I wake up
Baby, baby, baby, oh
Been thinking 'bout it all day
What you gonna do about it now?
Baby, baby, baby, no one else compares
Your the only one for me
And I'll be your top when you're feeling low
You're my girlfriend
Boyfriend, boyfriend
Boyfriend, boyfriend
Boyfriend, boyfriend
Boyfriend, boyfriend
