Rihanna and Chris Brown tweaked the noses of do-gooders, moralizers and scolds everywhere by releasing a remixed version of her song “Birthday Cake,” featuring new sexually charged verses by her and her abusive ex-boyfriend.

Rihanna who turned 24 yesterday (Feb. 20) has apparently been seeing Brown on the sly although the extent of their relationship is unknown. Brown is supposed to be dating model Karrueche Tran.

Her producers let it be known last night on Twitter that Brown contributed to her remix. Brown also shared a link on Twitter revealing that Rihanna had returned the favor on a re-do of his Fortune single “Turn Up the Music.”

Birthday Cake Remix New Lyrics

Ooh baby, I like it
You so excited
Don’t try to hide it
I’mma make you my bitch
Cake, cake, cake, cake
I know you wanna bite this
Its so enticin’
Nothin’ else like this
I’mma make you my bitch

Chris Brown
Girl I wanna fu*k you right now
Been a long time I been missin’ your body
Let me, let me turn the lights down
When I, when I go down, it’s a private party
It’s not even her birthday, but I wanna lick the icing off
Give it to her in the worst way
I wanna blow the candles out

As it turns out, Barbadian singer and the rap star may have been secretly hooking up for much of the past year, according to USWeekly. “Rihanna loves to live dangerously,” a friend told the magazine. “Talking to and hooking up with Chris is all part of that.”

Brown infamously beat up Rihanna just before the Grammy Awards in 2009. He eventually pleaded guilty to felony assault and was sentenced to five years probation, which he is still serving, plus community service. But it seems clear he hasn’t learned much from the experience.

He still can’t manage his anger. He flew off the handle before the American Music Awards in November, because a fan asked him about the assault on Twitter. He replied in a profanity laced rant. “I know a lot of you wack a** (OLD) celebrities probably wanna f*** my ex, but talking s*** on me wont get you far! and to be REALLY HONEST, ya’ll wonder why n**** spazzes all the time?” he wrote.

Before that last March, he went ballistic after an ABC interview because host Robyn Roberts brought up the Rihanna incident. Afterward, he could be heard screaming in his dressing room amid loud crashing sounds. He threw a chair at a window, shattering it and sending shards of glass to the street below.

He’s irked because people just can’t let the incident go. But it’s also clear his attitude hasn’t changed much. After winning a Grammy earlier this month for his album F.A.M.E, he fired off another belligerent Tweet: “HATE ALL U WANT BECUZ I GOT A GRAMMY Now! That’s the ultimate F**** OFF!”

Obviously, Brown and Rihanna can, and will, do whatever they want. But that doesn’t mean their behavior will come without consequences, whether its continued public condemnation or damage to their careers.

The problem is neither is close to mature enough to handle the fallout.
