Baby Baby Baby Baby
Oh oh oh oh
Everyday I keep on missing you
Oh oh oh oh
Girl you know I miss you so
Oh oh oh oh
I can't stop I can't stop
Thinking about you all over me
Oh oh oh oh
Girl you know I'm down for you
Girl, I ain't trying to rush it
But I want it, want it, want it
You can tell I'm all into it
You can feel it, feel it, feel it
In my system, let me show you
That I'm feeling it, wanting it, wanting it
And baby baby baby baby baby baby
Baby you got me like junior in a gangsta phase
Girl, your body's fine, it's out of control now (so addictive)
Every time we talk I can't say enough now (about enough)
Just ain't like you, been acting weird now (got to get next to you)
Your vibe today is what I need to win you over (come on)
Everyday I keep on missing you (missing you)
Oh oh oh oh (I miss you)
Girl you know I miss you so (miss you)
Oh oh oh oh (so baby)
I can't stop I can't stop (can't stop)
Thinking about you all over me (over me)
Oh oh oh oh (girl)
Girl you know I'm down for you (down for you)
Yeah, I ain't trying to rush it (ain't trying to rush it)
But I want it, want it, want it (want it)
And baby, baby, baby, baby, baby, baby (oh)
I'm feeling like junior in a gangsta phase (gangsta phase)
And I ain't tryna rush this thing (uh-huh)
But your body got me so addicted (got me so addicted)
And every time we talk I just can't get enough of your love (your love)
Yeah, you got a way with words (got a way with words)
And I ain't tryna be rude (ain't tryna be rude)
But I gotta let you know how I feel (how I feel)
Yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah (come on) 你可以根據以上歌詞自行判斷哪些地方出現“Baby Baby”。
