Baby, I don't know when the danger came 
I wanna find someone that I can blame 
Call the doctor cause I am sick in love 
And I can't help it 

Baby, I'm worried about my mental state 
Don't know if I'll recuperate 
Think it's serious, gone from bad to worse 
And I'm in trouble 

(Oh) I think I'm coming down with something 
(Yeah) I know it, gonna need your medicine 
(Oh) So help me now, I'm freaking out, lover 

This love is serious (everybody knows I'm mad for you) 
You get me seriously out of my mind 
And I am so into us (not gonna let no one get hold of you) 
Baby, baby 
Cause this love is serious, we're seriously onto something 
Serious 

Lover, you love me like no one can 
So if I'm crazy, hope you understand 
Hurry doctor come, need to get me some 
You know what time it is 

(Oh) I think I'm coming down with something 
(Yeah) I know it, gonna need your medicine 
(Oh) So help me now, I'm freaking out, lover 

This love is serious (everybody knows I'm mad for you) 
You get me seriously out of my mind 
And I am so into us (let no one get hold of you) 
Baby, you're mine (you're seriously fine) 

And you know I can't stand 
How the girls all wanna be getting all up in my place 
So get off of my man and don't try to mess with me 
Cause this love is serious, we're seriously onto something 
We're serious, uh-oh, uh-oh 

You got me so delirious, I'm under your control 
Point it at me if you must, your arrow's got me poisoned 
Tell me what my treatment is, your love's got me insane 
My prescription is your kiss, and boy you got me wantin' it 
(S-E-R-I-O-U-S) 
[2x] 

This love is serious (everybody knows I'm mad for you) 
You get me seriously out of my mind 
And I am so into us (let no one get hold of you) 
Baby, you're mine (you're seriously fine)
