[Intro: Ally]
Hey hey, yeah
Hey hey

[Verse 1: Ally & All & Normani & Lauren & (Camila) & {Dinah}]
People say
We shouldn't be together
And they don't know about forever
But I say that they don't know what they're talk talk talking about
Talk, talk talking about
(This love)
Is only getting stronger
And I ain't waiting any longer
{I just wanna tell the world that you're my boy, oh ah}

[Chorus: Camila & All]
They don't know about the things we do
(They don't know, they don't know)
They don't know about the I love you's
(They don't know, they don't know)
But I bet you if they only knew
(They don't know, they don't know)
They would just be jealous of us
(Just be jealous of us)
They don't know about the up all nights
(They don't know, they don't know)
They don't know I've waited all my life
(They don't know, they don't know)
Just to find a love that feels this right
(They don't know, they don't know)
Baby they don't know about, they don't know about us
(They don't know, they don't know)
About us

[Verse 2: Ally & All & Normani & Lauren]
Just one touch
And I was a believer
And every day is a little sweeter
It gets better, keeps getting better all the time

[Chorus: Camila & All]
They don't know about the things we do
(They don't know, they don't know)
They don't know about the I love you's
(They don't know, they don't know)
But I bet you if they only knew
(They don't know, they don't know)
They would just be jealous of us
(Just be jealous of us)
They don't know about the up all nights
(They don't know, they don't know)
They don't know I've waited all my life
(They don't know, they don't know)
Just to find a love that feels this right
(They don't know, they don't know)
Baby they don't know about, they don't know about us

[End: All & Camila]
Hey, hey
Baby they don't know about us
Hey, hey
'Cause we like to party
Hey, hey
Yeah, we like to party
Hey, hey
Baby they don't know about
They don't know about us
