While some say it may be a party to celebrate Jay-Z's new deal with Live Nation, The Insider has learned that preparations for a big event are being laid out right now at the Tribeca apartments in New York that could very well be for his rumored wedding to Beyonce! A box from Amy's Orchids was just delivered and CC Rental has been delivering as well. Busy workers are building an indoor tent with an all-white theme and the Roman numeral IV. We're told the event will be for about 30 people. The "magic hour" -- when all the workers need to be out -- is 3 p.m.

From People.com: For Beyoncé and Jay-Z, April showers brought flowers – and a possible wedding. On a rainy Friday in New York City, crews delivered floral arrangements, video equipment and a tent into Jay-Z's Tribeca apartment building. The wedding buzz began when the couple went to get a marriage license at a village hall in Scarsdale, N.Y., on Tuesday. "It's [happening] tonight," says a source. "A lot of their friends are booking hotel rooms." Early Friday morning, workers erected a white tent atop the building, where Jay-Z owns a penthouse apartment. Not long after, an SUV carrying photo and video equipment arrived, followed by floral deliveries.

More evidence of an impending wedding? Likely guests have been gathering in New York. Producer Rodney Jerkins, who is working on Beyoncée's new album and is a friend of Jay-Z's, zipped into town a couple of days ago. Beyoncé's former Destiny's Child bandmates, Kelly Rowland and Michelle Williams, are also here, coyly divulging in a YouTube video that they are camped out at The Four Seasons Hotel, giggling about "sisters" getting together.

And of course, there's Jay-Z, who was spotted hopping a flight from Boston, where he performed last night, to New York this morning. Friends of the couple say they are very eager for the nuptials to happen. "It's about time," says producer Dallas Austin. "I think it's great that they're getting married."

MORE UPDATES

FROM YBF.COM: YBF New York correspondents are currently on the scene around 195 Hudson St. (Jay-Z’s place) which is the rumored place Beyonce & Jay-Z wedding festivities are going down today. It’s a paparazzi and media zoo to the utmost power down there and we’ve definitely found out some interesting tidbits. Here’s what YBF has seen and heard so far while on the scene:

* Around 5p est today, a black SUV with full tinted windows flew through the crowd of media to enter the building’s garage. Only one paparazzo landed a pic of the unconfirmed woman inside. But she was by herself and purposely covering her face with a black and silver “Dereon like” hoodie.
* Another person was spotted entering the building who resembled Irv Gotti.
* 20 minutes later 8 black SUVs of the same kind exited the garage one right after the other. All SUVs were empty.
* Word on the street (from an unreliable source) was that the wedding was over and had taken place in a different location.
* But another word on the street (from a more reliable source) is that the wedding is actually taking place tonight. This would make more sense if that was indeed Bey in the first SUV.
* Word has it the SUVs all left to pick up guests and transport them back to Jay-Z’s place for a possible reception/party.
* Ironically, Dame Dash lives on the same street.
* Jay bought the penthouse for approx. $6 mill even though the building looks like crap from the outside.
* People were spotted setting up for “what looks like a party” under that white tent on the roof.

FROM THE INSIDER ONLINE: "The Insider"'s sources just spotted a man who might be JAY-Z entering the rapper's Tribeca residence through the garage in a black Cadillac Escalade. The man was dressed up and was holding a white cloth over his face. A neighbor of Jay-Z's told our sources that he was aware of the wedding, and that preparations for it have been in the works since Tuesday. He added that he's seen Jay-Z and BEYONCE a few times since they moved in to the apartment a week ago, and that they've been ideal neighbors.
