If you gossip about it, they will come. Or so it seems for Icelandic singer Björk and her artist husband, Matthew Barney. On August 12, one solitary neighbor tweeted that the pair was moving to Brooklyn Heights. The tweeter admitted he was starting a rumor, but the Brooklyn Heights Blog picked up on it, for fun. A week later, longtime borough chronicler (and Brooklyn Flea co-founder) Brownstoner upgraded the news from blather to bona fide. Though city records show the couple’s name newly attached to a four-bedroom, four-bath co-op on Henry Street (asking price: $4.25 million), some BHB commenters are reserving judgment until the deed is filed. (It’s gorgeous, but totally conventional. And it has a wraparound terrace just like their former downtown apartment.) From our angle, though, the move definitely appears to be real: According to Streeteasy, the one-bedroom, two-bath apartment that the couple owns on West Houston Street was put on the market a day before the Henry Street apartment pad went into contract. The price tag for the one-bedroom, two-bath, still available for Cremaster-loving, swan-dress devotees? $1.7 million.
