Carmelo Anthony was messing around with a woman who now claims she’s pregnant with his baby — and as you can imagine, his wife, La La, is pissed … TMZ Sports has learned. 

Multiple sources tell us … the other woman often works at a gentlemen’s club in NYC, and we’re told she’s claiming to be 6 and a half months pregnant with Melo’s child. 

We’re also told she has made it clear to Melo she expects him to kick in for medical expenses and other baby related costs. 

Sources close to both Melo and La La are telling us the marriage has been rocky for a while — and while the pregnancy wasn’t the tipping point, it certainly didn’t help.

So far, neither side has filed divorce papers but we’re told there’s virtually zero chance of a reconciliation. 

Just a perfect end to the Carmelo Anthony saga in New York. He has worn out his welcome with the fans, worn out his welcome with the Knicks, and now he goes for the triple crown with juicy stripper pregnancy scandal. You know when people say ” Oh, this city can eat you alive”? It’s never been more true. In this case, it swallowed Carmelo whole. Like a nice piece of sushi garnished with wasabi, ginger, and soy sauce. One bite. His career is winding down, is family is torn apart, and now he has to worry about some succubus stripper thinning out his wallet for the next 18 years. I think we need the summer Olympics bumped up a couple years, because right now Carmelo needs a gold medal like a junkie needs Narcan.

Need to know what strip club. Hoping it was Sue’s Rendezvous and we get a good look at this beauty once her identity is revealed. Huge downgrade from honey nut cheerios.
