Trina has some nerve hating on Khloe Kardashian for stealing French Montana away from her ... because Trina did the exact same thing to French's wife ... so claim friends of French (FOF).
Trina's blasting French and Khloe in a new song "F*** Love" ... "You can keep that purse, you can keep that whip, you can have that bitch."
But FOF say the song should have been called "Karma" ... because she started banging French while he was still married.
We're told French had feelings for Trina ... but she was never "his main girl" ... so it's a case of no harm, no foul.
Final shot ...FOF say Trina's new song is a lame attempt to jump start her career off French and Khloe.
