Houston Rockets guard Kevin Porter Jr. was busted in the Big Apple early Monday for allegedly assaulting his girlfriend — a former WNBA player — inside a Midtown hotel, authorities and police sources said.

Cops nabbed the 23-year-old pro baller at around 6:30 a.m. after receiving a 911 call for an assault at the four-star Millennium Hilton New York Hotel at 1 UN Plaza, according to the NYPD and police sources.

When officers arrived, they found Porter’s 26-year-old girlfriend Kysre Gondrezick — who previously played for the Indiana Fever and Chicago Sky teams — with a cut on her face and suffering neck pain, cops and sources said. 

The NBA player allegedly hit Gondrezick multiple times and placed his hands around her neck, cops said. 

The alleged assault took place after the couple went out Sunday night and later returned to the hotel, according to sources.

Gondrezick was sleeping when she woke up to her beau hitting her, the sources said. 

She was taken to a local hospital for a medical evaluation, and was listed in stable condition. 

Porter – whose full name is Bryan Kevin Porter Jr. – was charged with assault and strangulation, cops said.

He was awaiting arraignment in Manhattan Criminal Court Monday afternoon.

Porter signed a $63.4M contract with the Rockets in 2022.

Representatives for the Houston Rockets did not immediately respond to a request for comment.
