Ariana Grande and Pete Davidson have been moving fast since they hooked up, and now it's onward and upward in the form of a super deluxe apartment in the sky. The newly engaged couple just moved into a $16 MILLION apartment in Manhattan's Chelsea neighborhood ... it's a new luxury complex designed by famed architect Zaha Hadid. Their unit is more than 4,000 sq. ft. with 5 beds and 4.5 baths, and features amazing views of the city and the Empire State Building. The complex has a fitness center, a 75-foot sky lit pool, a private IMAX theater ... and Sting as their neighbor.
