PJ Tucker Married!? Wife Slams Blac Chyna As 'Homewrecking Thot'

blacchyna: "6'6."

That's likely Tucker's arm as the new "power" couple take sexy selfies together. And yes - the Phoenix Suns player measures in at 6'5" (close enough).

And they're partying a lot together, too:

blacchyna: "Yes Zaddyyy... All day n*gga!"

There's that trouble-brewing watch again...

Tucker is a 29-year-old small forward/shooting guard who just signed a whopping three year, $16 million contract.He now has more than 32,000 followers on Instagram and counting. And he likes to go shopping for high-end gear... a lot:

Not too shabby - Chyna definitely knows how to step-up her game! But is this blossoming romance for real, or just a fun and flirty fling?

Meanwhile, the "Rack City" emcee isn't having such great luck. Apparently, he recently broke things off with 17-year-old girlfriend Kylie Jenner because the relationship was moving too fast. He just got intimidated and now wants to enjoy his freedom. A supposed Life & Style insider reveals:

"The thought of Kylie being pregnant really scared the hell out of Tyga... [But] she never saw the end coming... [She's] devastated about the split" (via HollywoodLife.com).

But no - the "Keeping Up With The Kardashians" youngers is not pregnant.

Such rumors remain unconfirmed - in fact, things still seem to be going pretty well between the pair. But did Chyna just up the game by snagging a "more successful" boy toy? Now her cyber fame continues skyrocketing - wonder if that really bothers Tyga?

 Yes Zaddyyy .... All day nigga !
