By midnight, People.com was quoting a source as confirming the wedding happened early Friday evening, followed by a party at the downtown Manhattan loft belonging to the 38-year-old rapper, whose real name is Shawn Carter.
But, by early Saturday morning there was still no official confirmation that the couple were married.
Signs of preparations started early in the day. Gossip sites showed photos of orchids being delivered to the building and of a tent set up on what was said to be the balcony of Carter's penthouse loft.
2The paparazzi were there anyway, making it difficult for the Mercedes and SUVs carrying party guests to make their way into the building's garage. Actress Gwyneth Paltrow, a friend of Knowles, was photographed arriving at the scene.
TMZ even streamed the action live on their Web site - until their battery ran out.
"We're so lame, R.I.P. our dead battery, sorry!" read a message on their site with an image of a tombstone.
On April Fool's Day, no less.
The Scarsdale county clerk did not return requests for comment to The Showbuzz. Knowles' publicist had "no comment" on the matter.
The couple have been dating for five years.
