Karrueche Tran Cheating Scandal, Chris Brown Instagram Rant & Apology Explodes! Rihanna's Ex Blasts Drake & A$AP Rocky 'Groupie' Amid FINAL Break-Up?

And all this time, several fans assumed that Chris Brown was the one cheating...

Turns out, on-and-off again girlfriend Karrueche Tran was allegedly "disloyal" throughout their happy (yet somewhat tumultuous) relationship!

But here's the real kicker... she apparently hooked-up with Breezy's ultimate hip-hop enemy, Drake...

Over the weekend, the X crooner shared this heated message on Instagram:

"We've got scars, some of them u gave me, some of them I've caused. That ride or die act we have been fooling the world with obviously ain't working. I was locked up for damn near 4 months and only got 1 visit from you while u was hosting parties and taking secret trips to Toronto, going on dates with Drake! When this relationship first started u knew what it was and even participated in threesomes. I slowed all that sh*t down. So let's not try to save face for public opinion because I don't need to play victim so people can take my side. All these celebrity n*ggas ain't sh*t and focus only on themselves. I made it clear to the world who my girl was and made your life equal to mine even at the cost of me not focusing on my career at times." He added, "So miss me wit the bullsh*t. Now yall know the real."

Woah.

The aspiring 26-year-old model didn't keep quiet. She rather mockfully responded on Twitter with:

@karrueche: "N*ggas be in they feelings when you break up with them lol."

@karrueche: "Once you find strength within yourself, it's hard to allow any type of bs around you. I refuse to be..."

Her official Instagram account was later disabled, but apparently Brown had a slight change of heart following his harsh words. He deleted his original post and replaced it with this heartfelt apology:

chrisbrownofficial: "Being young and dumb is one of my strong suits and emotional at best. I love hard and react impulsively when I'm hurt at times. I don't think social media is a place to air out or hash out personal problems and a nigga feel hella WACK for doing it. So I AM APOLOGIZING I live in a glass house and the same shit that makes me great also is my curse. Everybody know I love that girl. I don't care how my image my look to the public because I'm still gonna be the best at what I do. I just want baby girl to know I apologize!"

Meanwhile, a "snitch" for thei infamous gossip webloid MediaTakeOut.com explains that things exploded on Friday (December 5) when Tran was spotted "flirting" with yet another rapper, A$AP Rocky. Rumors suggest she's just a plain ol' "groupie."

Oh, and here's Trans supposed side of the story... according to her "good friend" Joey.

Of course, Drizzy remains mum on social media. Probably the smart thing for now.

So, is this latest break-up official - do MstarsNews readers really think Tran cheated with Drake (and maybe several other musicians)? Stay tuned!
