The daughter of Hunter Biden’s “sugar brother” Kevin Morris accused the first son of “taking advantage” of the millionaire Hollywood lawyer, The Post has learned.

Dulcie Lou Morris, 23, dressed down the first son face-to-face for taking millions from her father for his legal bills.

Morris, 60, is a Hollywood entertainment lawyer and Democratic donor who began paying Hunter Biden’s debts weeks after meeting him at a fundraiser for then-candidate Joe Biden in Brentwood, California, in 2019.

On Monday, Morris showed up in Wilmington, Delaware, as part of the Biden entourage for the first day of Hunter’s gun trial.

Also present in a show of support were First Lady Jill Biden and first daughter Ashley Biden and Melissa Cohen, Hunter’s second wife.

The first son denies three felony charges stemming from the alleged illegal possession of a gun in 2018, while he was a drug user.

He is accused of failing to disclose he was on drugs when he bought the .38 caliber Colt Cobra revolver at a Delaware gun shop at a time when he was smoking crack every 15 minutes, according to his own memoir, Beautiful Things.

While the first son’s family rallied around him, Morris’s family have attacked both Hunter and Morris himself.

“His entire family has abandoned him because they were livid when they found out he was bankrolling everything,” a source close to the Morris family told The Post.

Morris’s daughter Dulcie Lou even confronted Hunter Biden recently, telling him to “stop taking advantage of my father,” the source said.

Last month, Politico reported that Morris told his legal associates that he has run out of cash to help fund Biden’s defense.

Abbe Lowell, Biden’s main attorney, had sought to postpone the Delaware trial last month over “strained” resources to handle two trials in different parts of the country.

Biden will go on trial accused of federal tax crime in Los Angeles, California, in September.

Lowell takes in between $850 per hour and more than $1,500 per hour, according to Politico.

It’s unclear how much Morris has spent on Biden, but a January letter to the House Oversight Committee from one of Morris’s attorneys suggests the figure is more than $6.5 million, including a $2.6 million loan to pay Biden’s debt to the IRS in 2021.

Most of the loans carry a five percent interest rate, the letter said.

Morris also found a “lavish” house for Biden and his wife Cheryl Cohen in Venice Beach, paying $17,500 a month from January 2020 to October, 15, 2020, according to transcripts from the House committee hearing.

“I have worked hard to create a life that has allowed me to help my family and friends when they have needed it, and I did so with Hunter,” Morris told the House committee.

In addition to paying for the first son’s personal expenses, Morris bought 13 of the self-taught artist’s paintings, totaling nearly $1 million.

And Morris is accused of spying on the filming of a documentary, entitled “My Son Hunter,” according to a complaint lodged with the State Bar of California.

In the complaint, filmmaker Phelim McAleer alleges that Morris flew on his private jet in November 2021 to Serbia, where the Hunter Biden biopic was being filmed, and pretended he was an independent documentary filmmaker producing content for “South Park streaming.”

A spokesperson for the State Bar of California said they could not confirm the existence or status of the investigation.

Morris made his fortune representing the co-creators of “South Park,” and other Hollywood celebrities, including Matthew McConaughey and Scarlett Johansson.

Calls to lawyers representing Hunter Biden and Kevin Morris were not returned Monday.

Dulcie Lou Morris refused comment Monday.
