In an unusual twist, the Post is reporting that the purchase was supposed to be kept top secret, presumably so Grammer's second wife, Camille Donatacci Grammer, does not use it against him in their ongoing divorce proceedings. He will be shacking up with the 28-year-old flight attendant he is now dating.

The apartment, according to Holly Parker and Tricia Ridell's Elliman listing, sprawls across 3,100-square-feet on half of the 19th floor, replete with those signature windows and a brooding Nouvel-designed fireplace. Wonder what he thinks of the stark lobby? The original asking price was $7.52 million.

Curbed spotted Grammer looking at an apartment just up the street, as well, in 200 11th Avenue, the Annabelle Selldorf building with its famous sky garages. He would have been more among his "kind" in that building, including Nicole Kidman and Domenico Dolce of Dolce & Gabana. But his new neighbors aren't nobodies, either, including the founder of the world's top webcam service and the son of British starchitect Richard Rogers. Plus, with plenty of penthouse and high-floor units left, 100 11th has more room than its neighbor for more blockbuster deals.
