[Intro: Lawrence]
I think my girlfriend is an alien
Invading force from Planet 10
Said she was from out of town
But I know what she meant...

[Verse: Lawrence & Phineas]
I know she's from another galaxy
I don't know just what she's a-doing with me!
She treats my love like a science experiment
Hubble-Bubble

[Pre-Chorus: Lawrence]
Does she love me for who I am?
Or does she want to put my brain in a can?
She can have it, cause I never want to be apart...
(Take my leg warmers, Max!)
From her alien heart!

[Chorus: Phineas, Ferb & Lawrence]
(She's got an alien) Heart!
(She's got an alien) Heart!
(She's got an alien) She's got an alien heart!
(She's got an alien) Heart!
(She's got an alien) Heart!
(She's got an alien) Heart!
[Bridge: Phineas, Ferb & Lawrence]
She's got an alien heart!
(She's got an alien) Pumps like the Dickens!

[Chorus: Phineas, Ferb & Lawrence]
(She's got an alien) She's got an alien heart!
(She's got an alien) Heart...
(She's got an alien) Heart...
(She's got an alien) She's got an alien heart...
