I wanna be your first and your last
The one to make you curse then laugh
I know that you've been hurt in the past
But baby you know I won't do that
Cause baby you're like a heartbeat, heartbeat
Ain't living without a heartbeat, heartbeat
Can't make it without a heartbeat, heartbeat
So baby you're like a heartbeat, heartbeat
Yeah yeah

Yea I feel it baby
Everytime [bad word] around I get to feeling crazy
Butterflies up in my stomach feel like I could fly
Cause I'm just so happy that I can call you mine
Cause when you're gone I'm feeling anxious cause I wanna see you
You got all these girls trippin' cause they wanna be you
Swagga mean and you're walk'll put a model to shame
Always down to have some fun but you ain't for the games
And now I'm fallin, now I'm falling girl and you're to blame
Tried chillin with other women it don't feel the same
Cause baby you're like the sun and the mist of rain
No matter what you're doing your shining do your thing
I'd be lying if I said that you weren't on my mind
Swear that when we together I want to freeze time
So even when I fell I ain't got nothing left
Whenever you go to leave I feel it in my chest (feel it beating less)

I wanna be your first and your last
The one to make you curse then laugh
I know that you've been hurt in the past
But baby you know I won't do that
Cause baby you're like a heartbeat, heartbeat
Ain't living without a heartbeat, heartbeat
Can't make it without a heartbeat, heartbeat
So baby you're like a heartbeat, heartbeat
Yeah yeah

x2
We be fighting just to make up
Know the dudes hatin yeah they hoping that we break up
We a dream couple but they hoping that we wake up
Wake up from our dream
Blow a couple dollars make proud you on my team
I seen a couple dimes but they just not you
Have me feeling pretty high but they can't top you
I tell 'em cut it out I just can't crop you
Got a fence around my heart but I just can't block you
Cause even when I'm stressed you'll be my masseuse
Kiss you on the lips to satisfy my sweet tooth
Cause when I'm feeling lost you know what to do
And when I'm feeling blind always help me see the [bad word] 
Long as you ain't never changing, you can be my main chick
You can be the girlie I be with and arranged with
We just pass haters we ain't in the same lane
With and when it's all over be the one I share a ring with (yeah)
