Looks like all that post-divorce refresh paid off — Porsha Williams just hard-launched her new girlfriend, and sis is glowing like she hit the jackpot!

In IG pics shared Friday — snapped in front of her Christmas tree — Porsha’s getting cradled from behind by her new GF, Sway The Pro (real name Patrice McKinney) … and the two look seriously smitten.

Porsha was radiating happiness while wishing her new boo a happy birthday — rocking a leopard-print dress and looking all kinds of stunning as she cozied up with Sway … who popped up in more pics from the carousel, including one where she’s planting a sweet kiss on Porsha’s cheek.

The ‘Real Housewives of Atlanta’ star has def moved on from ex-hubby Simon Guobadia — and it looks like Patrice is the one who stole the top spot … especially after Porsha said last month she’d been talking to two people: a man and a woman.

Speaking at CultureCon, she said they were both nice, normal people — not narcissists — which actually made it harder for her to open up, since her old patterns had her going all-in with love-bombing narcs in the past.
