Lil Mabu is a senior at Collegiate School, the nearly 400-year-old Manhattan prep that costs $60,000 a year.
The 17-year-old rapper’s real name is Matthew Peter DeLuca, and he lives at his parents’ five-bed, five-bath, 3,327-square foot condo on the Upper East Side. During school breaks or on weekends, he can escape to the Hamptons, where his family owns a 6,182-square foot manse in Water Mill. The two properties are worth close to $12 million total.
