Designer Marc Jacobs and his hot boyfriend Lorenzo Martone closed yesterday on their townhouse at Superior Ink in the Village, for which they paid $10.4 million and bought as a “white box” of empty space, reports The Post’s Jennifer Gould Keil. The Bethune Street townhouse has nearly 4,400 square feet and comes with a private elevator, rear terrace and yard and a roof terrace, and connects to the garage for ultimate privacy. Not bad, considering that Houston Rockets owner Leslie Alexander previously paid $25 million for his pad in the complex.
