[Intro: R. Kelly]
(One-two checka
Baby let me know what's up)

[Bridge: Aaliyah]
If you're wondering
You gotta let me know, baby
You don't have to worry
If you're wondering
You gotta let me know, baby
You don't have to worry

[Verse 1: Aaliyah]
Boy, I know that you've been having doubts
That I am gonna go and leave you lonely
Come over here and let me make your love come down
I know just what you need
So boy have no fear
I am going to be here forever a day
For you

[Bridge:]
If you're wondering
You gotta let me know, baby
You don't have to worry
If you're wondering
You gotta let me know, baby
You don't have to worry

[Verse 2: R. Kelly]
(One-two checka
Baby let me know what's up)
Now you know that I would do anything for the love of you, baby
Because your kisses drive me wild
Ooh, child
Is it ok if I stay a while?

[Interlude: R. Kelly and (Aaliyah)]
Haha, yo, what cha doin' baby boo? (chillin')
You just trippin, know what i'm saying
Hey, get in your jeep, come pick me up, ight
Come give me a lil' somethin'
(If you're wondering)

[Bridge]
If you're wondering
You gotta let me know, baby
You don't have to worry
If you're wondering
You gotta let me know, baby
You don't have to worry
