Lyrics:

“Tell Him” is featured in Sadie Hawkins, the eleventh episode of Season Four. It is sung by the New Directions Girls, with Brittany (Heather Morris) and Marley (Melissa Benoist) singing lead.
I know something about love

You've gotta want it bad

If that guy's got into your blood

Go out and get him

If you want him to be (Do, do-do, do, do-do)
The very part of you (Do, do-do, do, do-do)
Makes you want to breathe (Do, do-do, do, do-do)
Here's the thing to do (Do, do-do, do, do-do)

Tell him that you're never gonna leave him
Tell him that you're always gonna love him
Tell him, tell him, tell him, tell him right now

I know something about love

You gotta show it and
Make him see the moon up above

Reach out and get him
If you want him to be (Do, do-do, do, do-do)
Always by your side (Do, do-do, do, do-do)
If you want him to (Do, do-do, do, do-do)
Only think of you (Do, do-do, do, do-do)

Tell him that you're never gonna leave him
Tell him that you're always gonna love him
Tell him, tell him, tell him, tell him right now

Ever since the world began
It's been that way for man
And women were created

To make love their destiny
Then why should true love be
So complicated
Oh, yeah, oh

I know something about love
You gotta take his hand
Show him what the world is made of
One kiss will prove it

If you want him to be (Do, do-do, do, do-do)
Always by your side (Do, do-do, do, do-do)
Take his hand tonight (Do, do-do, do, do-do)
Swallow your foolish pride (Do, do-do, do, do-do)

Tell him that you're never gonna leave him
Tell him that you're always gonna love him
Tell him, tell him, tell him, tell him right now

Oh, you have to tell him now

Tell him that you're never gonna leave him (Oh, yeah)
Tell him that you're always gonna love him (Yeah)
Tell him, tell him, tell him, tell him right now

Girl, you gotta tell him right now

Tell him that you're never gonna leave him (Oh, yeah)
Tell him that you're always gonna love him (Yeah)
Tell him, tell him, tell him, tell him right now

Just take his hand in yours and tell him

Tell him, tell him, tell him, tell him right now

Just take his hand in yours and tell him

Tell him, tell him, tell him (Tell him right now)
