Jordin Sparks Rips Jason Derulo "You Ungrateful Son Of Bitch"

Jordin Sparks puts even Taylor Swift to shame by 

mercilessly going after ex-BF Jason Derulo, calling 

him out as a vengeful ingrate. Sparks' SCUD missile 

takes the form of a mixtape, "#BYEFELICIA," featuring 

"How Bout Now (Remix)" ... it's a Drake song 

reworked to rip Derulo.

"Member I deleted all my other guys numbers on my 

phone for you. Member when you broke your neck 

and I had to wash your back for you. You probably 

don't remember half the shit that i did for you."

And it goes on ...

"Once you blew up, head got big and you started 

changing.

Can't believe all the things that you started saying.

Like I'm with you for your fame and your name. 

What?"

The couple split back in September after a 3-year 

romance. After the split Jason trashed Jordin, saying 

she was pressuring him to marry her.
