Bobbi Kristina Brown -- Whitney Houston's Daughter Reportedly EVICTED ... Leaves Ultra-Bitchy Note

Bobbi Kristina Brown -- Whitney Houston's daughter -- left a handwritten letter for her neighbors after she was evicted from her Georgia apartment ... AND IT'S NASTY!!!

The note reads ...

"Thanks

You are sh*t at the bottom of our shoe.

Thank You for making a hard year harder.

You are a miserable couple and always will be.

You were honored to have us living above you and you couldn't stand such a young beautiful couple far more successful than you ever will be.

I pray your misery doesn't rub off on your innocent little baby."

The neighbor who got the note was Joshua Morse -- who told 11alive.com he and his wife had filed at least 10 noise complaints against Bobbi Kristina because she was an absolute nightmare of a neighbor.

Morse says BK has officially moved out of the complex.
