[Verse 1]
You never took our love too seriously
You were just too good at pretending
It was all about you always hurting me
I never once thought of complaining

[Pre-Chorus]
Been doing this for so long
Tired of hearing the same song
You got me done tryna talk
Every time your mouth moves, it's lies, lies, lies

[Chorus]
Heartless, heartless
You can't help it, your life is so selfish
Heartless, heartless
You know, you know you hurt me
Heartless (heartless), heartless (heartless)
(Don't know what to do) Heartless
I just can't do this anymore
Ooh, heartless

[Verse 2]
Everyone knew I was too good for you
But you wouldn't even understand that
It was never in your nature to be true
To know why I just couldn't face it
[Pre-Chorus]
Been doing this for so long
Tired of hearing the same song
You got me done tryna talk
Every time your mouth moves, it's lies, lies, lies

[Chorus]
Heartless, heartless
You can't help it, your life is so selfish
Heartless, heartless
You know, you know you hurt me
Heartless (heartless), heartless (heartless)
(Don't know what to do) Heartless
I just can't do this anymore
Ooh, heartless

[Bridge]
You know you're just too stuck on yourself
Maybe you'd be better for someone else
Got no time for wishing for something that will never be
It's time for me to let you be what you'll be
And maybe you can be the one that got away, away
Cause you're heartless (heartless, heartless)
Oh, no (heartless, heartless)
Heartless
[Chorus]
Heartless, heartless
You can't help it, your life is so selfish
Heartless, heartless
You know, you know you hurt me
Heartless (heartless), heartless (heartless)
(Don't know what to do) Heartless
I just can't do this anymore
Ooh, heartless

[Outro]
(Heartless, heartless) Heartless
(Heartless, heartless) So heartless
So heartless, so heartless
