Help pl0x!!!

My wife and I recently had sex in the bathtub a few days ago. Needless to say, she was making quite a bit of noise.
I thought my daughter, who is 5-years-old, was asleep that night. Apparently, I was wrong.
The next morning, my daughter asked me what the noise was last night and I told her it was my wife "singing". Now, my daughter can't stop "singing" in the bathroom.

What can I do to make her stop?

LOL, fail..

And fake. ^^

But funny.

Fucking Troll.
Tell her, her singing sucks, and she should take up hunting.
