Jay-Z & Beyonce set to marry today?

Are Jay-Z & Beyonce set to tie the knot tonight?

It certainly looks that way!

"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 Beynce Knowles," reports The Insider. "A box from Amy's Orchids was just delivered and CC Rental has been delivering as well."

Buzz of a wedding began when the couple -- who have been dating for six years -- 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."

Several likely guests have been gathering in New York. Producer Rodney Jerkins, who is working on Beyonce's new album and is a friend of Jay-Z's, flew into town a couple of days ago.
