A New Jersey yoga instructor came forward Thursday to accuse Donald Trump of inappropriately touching her 18 years ago.

Karena Virginia, 45, said she ran into Trump at the US Open tennis tournament in Flushing in 1998 when he allegedly made the lewd move.

Virginia, appearing alongside celebrity attorney Gloria Allred at the London Hotel in New York, told reporters that Trump came out to her as she waited for a car to pick her up.

He remarked to a group of men around him, “Hey, look at this one” and “We haven’t seen her before, look at those legs,” according to Virginia.

That’s when he allegedly grabbed her right arm and touched her breast.

“I was in shock. I flinched. ‘Don’t you know who I am, don’t you know who I am.’ That’s what he said to me,” Virginia recounted. “I felt intimidated and I felt powerless.”

Virginia said her clothing of that day added to her embarrassment.

“I felt ashamed that I was wearing a short dress and high heels,” she said. “That feeling of shame stayed with me for a while and it made me disinclined to wear short dresses or high heels.”

Virginia is the 10th woman to accuse Trump of inappropriate sexual contact since the second presidential debate — when the GOP nominee insisted he had never groped or touched a woman against her will.

“Mr. Trump, perhaps you do not remember me, or what you did to me so many years ago. But I can assure you that I remember you and what you did to me as though it was yesterday,” Virginia said as she choked back tears.

“Your random moment of sexual pleasure came at my expense and it affected me greatly.”

Allred, a Hillary Clinton supporter and delegate to this past summer’s Democratic National Convention, insisted she had no contact with the former first lady’s campaign regarding this client.

The Trump campaign dismissed Virginia’s allegations as a political stunt.

“Discredited political operative Gloria Allred, in another coordinated, publicity-seeking attack with the Clinton campaign, will stop at nothing to smear Mr. Trump,” said Jessica Ditto, deputy communications director of Trump’s campaign.

“Give me a break. Voters are tired of these circus-like antics and reject these fictional stories and the clear efforts to benefit Hillary Clinton.”

Virginia identifies herself as a yoga instructor, married with kids and living in the suburbs of New York, according to her personal website.

She had mentioned Trump — and an alleged shady encounter with him — earlier this month on her Facebook page.

“I have spent time with Donald Trump. I have also spent moments with his wife,” she wrote on Oct. 8.

“I have also been hit on by Donald Trump in a way that I do not want to write about on social media.”
