Paris Hilton sported a Beverly Hills sweatshirt when she touched down in Monaco this week with her $13,000 Pomeranian pooch, Prince Hilton The Pom.

Might we suggest her next sweatshirt purchase be “I Heart NY”?

The DJ and business mogul — she recently launched her 17th perfume and has made $2 billion in fragrance sales alone — has just bought a snazzy penthouse in NoHo, and knew how to negotiate here, too.

Hilton paid just under $3.9 million for the 2,400-square-foot, two-bedroom, two-bathroom unit at 737 Broadway.

The former warehouse, built in 1867, is a cast-iron beauty that is aging gracefully.

The full-floor homes were designed by architect Karl Fischer with interior designs by Andres Escobar. The apartment has wide-plank oak floors, high ceilings and two skylights, along with a floor-to-ceiling gas fireplace in white Calcutta marble, a chef’s kitchen, master suite with spa bath and a Crestron system to control it all.

Hilton’s broker, Douglas Elliman Jared Seligman, declined to comment, as did listing broker Raphael De Niro, also of Elliman.
