[Intro: Fergie]
One plus one plus one equals three
One plus one equals two
One plus three equals four (One, four, one, four, one)
One plus one plus one equals three
Three plus one equals four equals B-E-P, bitch

[Chorus: will.i.am, Fergie, Both]
Love... love...
Is a simple little melody
Is a simple little melody
To me...
And this is what it sounds like
La... la-la-la-la-la-la, la-la
La-la-la-la la, la-la
La-la-la-la...

[Verse 1: will.i.am]
Baby, why can't it be simple?
Four letters don't gotta be stressful
Thought love was the reason we was here fo'
Turn around, and you givin’ me an earful
That's a no-no, gotta go though
I meant that I acted kinda so-so
That don't mean that you gotta act loco
That's why you callin' me up on ya photo
Stop blowin' me up on my phone, yo
And you are stressing when I say, "Yo"
I think you still owe me back on the low, yo
You keep blowin' me up, keep blowin' me up
God damn it, and, girl, I really miss ya
God damn it, and, girl, I wanna kiss ya
God damn, why it so many issues?
Ease up, baby, ease up, baby, 'cause
[Chorus: will.i.am, Fergie, Both]
Love, love
Is a simple little melody
Is a simple little melody
To me
And this is what it sounds like
La, la-la-la-la-la-la, la-la
La-la-la-la la, la-la
La-la-la-la

[Verse 2: will.i.am, Fergie]
Love ain't technological like AutoBot, AutoBot
Love ain't robotic like AutoBot, AutoBot
Love ain't complicated like arithmetic, 'rithmetic
Love is stimulatin', let me stimulate and tickle it
Love is elementary like one-two-three, one-two-three
Love is really simple just like A-B-C, A-B-C
Love ain't technological
Love ain't technological (Technological)
Love ain't robotic like AutoBot, AutoBot
Love ain't robotic like AutoBot, AutoBot
Love ain't complicated like arithmetic, 'rithmetic
Love is stimulatin’, let me stimulate and tickle it
Tickle it, tickle it, tickle it, tickle it
Hahaha
[Outro: Fergie]
One plus one plus one equals three
One plus one equals two
One plus three equals four
One plus one plus one
One plus one plus one equals three
Three plus one equals four equals B-E-P, bitch
