"And I know we don't speak no more. But I just wanna tell you I'm sorry/ For f——'round with Keisha and MaKayla/ For all the Georgia peaches in Decatur/ For all these b—-es in the elevator/ I just want you to love me/ Yeah baby don't test me/ You know I'll do it."

And in case you're still confused about who he's referencing, he continues, "You want me to say your name girl?/ Okay, Karrueche!"

The duo, who dated on-and-off for four years, broke up in March 2015 after it was revealed that Chris had fathered a child with another woman. The 27-year-old hasn't publicly responded to the song.
