Chris Brown is BLASTING Rihanna for cheating on him during the relationship with rapper Drake in his new song Favorite Girl.

Here are some of the lyrics, courtesy of our pals over at The Grape Juice blog::

Drake would say you’re the best he ever had . . .
Everywhere we go, rumors follow…
yet I still love you

Then later Chris says:

Should have known you’d break my heart . . .
You were the first to play the game…
Though I was wrong for cheating in the beginning

And then later:

I was wrong for writing Disturbia
