Kevin Morris, an entertainment attorney and novelist who earned a fortune representing the co-creators of “South Park” and won a Tony award as the co-producer of “The Book of Mormon,” footed Hunter Biden’s overdue taxes totaling over $2 million — more than twice that which was previously reported, a source familiar with conversations between the two told the Post.

Morris, whom Hunter Biden’s friends call his latest “sugar brother,” has also been funding the 52-year-old’s lifestyle in Los Angeles — including his rent and living expenses, the source said.

The attorney has also been advising the president’s son on how to structure his art sales, according to the source.
