The blunt-smoking wannabe rapper who defended his wealthy parents when they were exposed in the wide-ranging college admissions bribery scandal was busted this week for attacking his father, The Post has learned.

Malcolm Abbott allegedly pushed, kicked, bit and whacked his father with a ruler during the assault at their Fifth Avenue home Sunday afternoon, police sources told The Post.

Cops busted him two days later at a nearby police precinct and slapped him with a felony assault charge, authorities said.

Malcom Abbott’s parents, New York beverage scion Gregory Abbott and Marcia Abbott, pleaded guilty earlier this week to paying $125,000 to doctor their daughter’s college entrance scores as part of the nationwide college admissions cheating scandal. The each face a year and one day in jail for the scheme.

In March, Malcolm Abbott, a wannabe rapper who goes by “Billa,” defended his parents while toking on a blunt outside their building that overlooks the Metropolitan Museum of Art.

“They’re blowing this whole thing out of proportion,” Malcolm Abbott told The Post in between drags from the blunt. “I believe everyone has a right to go to college, man.”

Billa then plugged his album.

“Check out my CD, ‘Cheese and Crackers,’” he said of the five-track record, which includes songs in which Abbott raps about “growing up f—-d-up on Fifth Avenue” and hanging “outside the prep school.”
