Last night around midnight, just as I was turning in for the evening, I received a text message from a very well-connected industry source. The text read simply: “It’s official. They’re back dating!”

“They who?” I replied — knowing full well who he meant.

“Rhi/Cb” he texted back. The ‘Rhi/Cb’ was Rihanna and Chris Brown. I was dumbfounded. I knew Brown was featured on the full length version of Rihanna’s “Birthday Cake” track off her current album. And I knew they had been seen partying at the same night spots in LA. But this industry source had assured me that the rumors of Rihanna and Chris Brown getting back together were untrue.

So why the sudden reversal of information?

My theory is this: Rihanna (or someone in her camp) read this Blind Item and started to buck at the realization that not only does she have to share Brown with his current long-suffering girlfriend, Karrueche Tran — but she’s also sharing him with Lil Wayne’s baby mama, Sarah ViVan too!

My industry source, who is connected with Rihanna’s record label, probably doesn’t want the information about Brown and Sarah to grow legs, since this would not be beneficial to the promotion and marketing of the “Birthday Cake” track.

In fact, the presence of Sarah in Brown’s life muddy’s up the waters considerably. Because Sarah is no light-weight jump off — she tends to get who she wants. And Sarah didn’t fly all the way from Atlanta to LA to NOT get her man.

My sources tells me that Sarah is tired of being known as just somebody’s baby mama. She wants to be claimed by a well-known star to make her legit in the public’s eye.

So we’re back to square one again: Rihanna, a fragile, malignant narcissist who is in desperate need of narcissistic supply, crawls back to not one, but two of her past sources of supply (Matt Kemp and Chris Brown).

It has been said that “You can abandon the narcissist – but the narcissist never abandons you.”

As for why Brown (another narcissist) would dump Karrueche, and replace her with Rihanna (or Sarah) — the answer is simple: The narcissist will quickly devalue one previously “adored” narcissistic supply, and replace her with someone he ranks higher.

It doesn’t take a psychiatrist to figure out that this story is not going to end well.
