The Upper West Side co-op owned by Sting and his wife Trudie Styler has gone into contract. No word if it went for its original asking price, $19 million. Whoever bought it will have some sexy ghosts to deal with.

In a 2007 interview about the manse, Styler admitted that she and her pop star hubby — known devotees of Tantric sex — enjoyed holding swingers orgy parties. Wooftie! She later denied the claim, but yeah right. Our advice to the new owners: wash the walls. Or, harvest them and genetically create a race of celebrity swinger clones. That works too! But be warned: Billy Joel used to own the apartment too. So. Here are some pics, via Halstead.
