A second woman has accused Antonio Brown of sexual misconduct, saying he inappropriately propositioned her at his Pittsburgh home in 2017 — standing behind her fully naked, holding a small towel over his genitals, while she painted, according to a new report.

The unnamed woman said the New England Patriots wide receiver came on to her after hiring her to paint a mural for him when he was playing with the Pittsburgh Steelers — and that their professional relationship soured when she rejected his advances, Sports Illustrated said Monday.

“He was flirty with me, but I paid him no mind because I was there on business. Plus, I had already seen him with multiple girls in the short time I was with him,” Brown’s accuser said.

“I was about 40 percent done on the second day, and I’m on my knees painting the bottom, and he walks up to me butt-ass naked, with a hand cloth covering his [penis] and starts having a conversation with me.

“I just kept my cool and kept painting,” she said. “After that, it all ended abruptly.”

She said Brown “ghosted” her after the incident and that her calls to his various assistants about being paid for other work went unanswered.

He paid her $1,000 a day for the two days’ work, but she said he still owes her $700 for a painting he purchased at the charity auction where they met in June 2017 and has also kept another one of her works.

In a statement released through his attorney, Brown denied all the allegations in the article and declined to comment further.

“[Brown] denies that he ever engaged in such activities. There will be no further comment at this time,” Darren Heitner tweeted Monday afternoon.

The painter is the second woman to accuse Brown of sexual misconduct this month, after the football player’s former trainer, Britney Taylor, accused him of rape in a civil lawsuit filed last week.

The painter is not seeking damages or pursuing charges but told Sports Illustrated she was “bothered by his behavior.”

She said friends who knew about her disturbing interaction with Brown alerted her to Taylor’s rape lawsuit against him.

Taylor reportedly will meet with NFL officials in New York on Monday as they conduct their own investigation into the alleged 2018 rape.

Also detailed in the Sports Illustrated report are multiple domestic-disturbance calls to the Pittsburgh home Brown shares with his longtime girlfriend, Chelsie Kyriss — the mother to three of his five children.

Police were called to the property in August 2017 after Kyriss accused Brown of throwing a bottle of cologne and container of lotion at her during an argument, the article said.

Kyriss was hesitant to pursue charges because she feared it would impact her partner’s career, police noted in their report.

In another incident in April 2018, police were called to Brown’s Sunny Isles, Fla., home after receiving a call that furniture was being thrown from the balcony of his 14th-floor apartment onto the street.

Cops said they found Brown “very agitated” and yelling that the building’s security had set him up.

In April, the athlete settled a lawsuit filed by the family of a 22-month-old tot who was nearly struck by the furniture as he walked with his grandfather below, the article said.

Brown has denied raping Taylor.
