He’s a major “player” — just not in politics.

Former New York City Mayor Bill de Blasio brought his new girlfriend, South Tucson mayor Roxanna Valenzuela, to Zohran Mamdani’s inauguration Thursday — then promptly sat next to his wife.

The left-leaning lothario arrived at the event with Valenzuela and introduced her to a Mamdani staffer before strolling into City Hall to greet Chirlaine McCray, with whom he’s still technically married.

The 64-year-old pol was then seated with McCray, with whom he shares two adult children, as his gal pal sat nowhere in sight.

Ex-Mayor Eric Adams was also seated next to McCray.

When de Blasio and Valenzuela — a mother of two — began their relationship, he was still seeing 41-year-old progressive activist Nomiki Konst, who was also in the audience Thursday.

In February, De Blasio revealed he was in a romantic relationship with Konst, saying she shares his political views and a desire to “cuddle.”  

He planned to spend Valentine’s Day snuggling with her and sipping wine, he told The Post, before they split up several months later.

De Blasio and McCray announced their split in July 2023, saying they still loved each other but no longer felt “lovey dovey.”

The couple blamed De Blasio’s long-derided political career for torpedoing their nearly three-decade marriage but said they wanted to remain partners.
