A source told People.com that singer Beyonce Knowles, 26, and rapper Jay-Z, 38, tied the knot early Friday evening, and then celebrated with a party at the rapper's home.
The Web site AllHipHop.com wrote that "an extremely close source" said the couple were indeed husband and wife.
Gossip sites showed photos of orchids being delivered to the building and a tent set up on what was said to be the balcony of Carter's home.
E! News quoted the owner of Amy's Orchids in Thailand as saying her company shipped orchids to New York for Knowles' and Carter's wedding Friday. A designer in the city used 60,000 orchids to create "eight-foot garlands that hung down from the ceiling to make the location look like an orchid palace."
2E! is the same network that's home to Ashton Kutcher's show "Pop Fiction" which sets up elaborate hoaxes with stars to fool the paparazzi.
Some skeptics said that the event might have simply been another one of Kutcher's stunts, or a celebration of the $150 million deal Carter made with Live Nation earlier this week.
Naysayers pointed out that there have been numerous wedding rumors about the couple in the past and that the timing was off since Carter had concert dates on the nights before and after the wedding.
The 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.
