An LA business executive who paid $400,000 to get his son into Georgetown University as a fake tennis recruit — and then sued the school to keep his kid enrolled — was sentenced to four months behind bars Thursday.

The fraud and conspiracy sentence for Stephen Semprevivo, 53, in the nationwide college admissions scandal came despite his tearful apology to the judge, in which he told his family and friends, “I’ve let you all down.”

“I deserve to be punished,” the dad tearfully told a federal judge in Boston, according to the Boston Globe. “I am fully remorseful.”

But the dad’s case had stood out in the sweeping scandal as particularly galling.

In May, his legal team sued Georgetown in a failed attempt to prevent the university from expelling his son, Adam — audaciously arguing that the elite school shared blame for the kid being admitted because it should have known his application was a fake. The suit was later withdrawn.

Adding to the chutzpah, on Thursday, one of his lawyers tried to soft-pedal the crime by claiming, “This is not a case where an African American tennis player was replaced with a white tennis player,” local WGBH News reported on Twitter.

Federal prosecutors had asked that the father be sentenced to far more time, calling for 13 months in prison and a $95,000 fine.

They noted that the bribe Semprevivo paid in 2016 was one of the biggest in the nationwide scheme masterminded by crooked college consultant William “Rick” Singer.

Semprevivo was “no passive wallflower” and knew the money he was donating to a bogus “charity” was in fact going to Singer, prosecutors argued Thursday — and yet the dad still fraudulently deducted the payoff from his taxes.

His lawyers described him as deeply remorseful, and had asked that he be sentenced to home confinement and 2,000 hours of community service.

In addition to the prison time, Semprevivo must pay a $100,000 fine and serve two years of supervised release plus perform 500 hours of community service.

He may have to pay additional restitution to Georgetown.

He is the third parent sentenced in the nationwide admissions scheme.

Actress Felicity Huffman was sentenced on Sept. 13 to 14 days in the slammer for admittedly paying $15,000 to inflate her daughter’s SAT scores. LA businessman Devin Sloane earlier this week received four months behind bars for paying $250,000 to get his son into the University of Southern California as a bogus water polo recruit.

Actress Lori Loughlin and her husband, fashion designer Mossimo Giannulli, have pleaded not guilty to charges they paid $500,000 to get their daughters into USC in the same scandal.
