“Blue Bloods” actress Bridget Moynahan, who’s pledged to spend $1.50 a day on food for a week to highlight poverty, just plunked down $4.63 million on a new Tribeca apartment, reports The Post’s Jennifer Gould Keil.

The three-bedroom, two-and-a-half-bath, loft-style pad is 2,793 square feet.

It comes with wide-plank walnut flooring, classic columns and open views from double-glazed arched windows.

Moynahan has a 6-year-old son, John, with her ex, Patriots quarterback Tom Brady.
