Who says there aren’t going to be any “celebrities” at the Trump inauguration!

Notorious pharma bro Martin Shkreli is headed to Washington, DC for President-elect Donald Trump’s inauguration – even if it is sans aplus-one.

A Brooklyn judge on Wednesday OK’d Shkreli’s travel to the nation’s capitol between Jan. 17 and 21 to attend a “social event,” according to new court filings.

Shkreli was booted off Twitter earlier this week after allegedly harassing Teen Vogue reporter Lauren Duca and asking her to accompany him to the inauguration.

The notorious 33-year-old price gouger was arrested in 2015 on securities fraud charges and, after getting sprung on $5 million bail, now has to abide by certain conditions of his release.

They include asking for the court’s permission to travel outside of the immediate New York City area.

Federal Judge Kiyo Matsumoto also approved Shkreli’s travel to attend two “speaking engagements” – one at the University of California, Davis in Los Angeles from Jan. 13 to 15, and another in Princeton New Jersey from Feb. 11 to 12.

Prosecutors didn’t object to Shkreli’s travel plans, the filing says.

Shkreli has denied harassing Duca, telling The Post: “I think Lauren is a very sweet lady. I wish she would attend the inauguration with me but instead she has chosen to tell people that I’m harassing her, which I think couldn’t be further from the truth.”

The 33-year-old became known as the “Most Hated Man in America” for jacking up the price of a potentially life-saving cancer drug by 5,000 percent.

His trial in the unrelated securities fraud case – where he’s accused of running an $11 million Ponzi-like scheme – is set to begin in June.
