Mrs. Beyoncé Z ?

It appears that Jay-Z and Beyoncé Knowles have finally tied the knot. There was a swirl of activity Friday at the rap mogul's Tribeca apartment. Delivery trucks funneled in and out of the building, dropping off silver candelabras and white flowers. A white tent was set up on the roof, and stars including Beyoncé's former Destiny's Child bandmates, Kelly Rowland and Michelle Williams, along with Gwyneth Paltrow, were spotted arriving.

The Web sites of celebrity magazines People and Us Weekly reported the couple married and threw a lavish but small party at the apartment Friday, citing unnamed sources who are friends with the pair. The Web sites reported their families attended the party.

Rumors circulated all week about the event after a report that the couple had taken out a marriage license in Scarsdale, N.Y. Representatives for Beyoncé and Jay-Z declined to comment on reports ahead of the event. Jay-Z's publicist had no comment Saturday.
