It appears that Jay-Z and Beyonce 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 Beyonce’s former Destiny’s Child bandmates, Kelly Rowland and Michelle Williams, along with Gwyneth Paltrow, were spotted arriving.

Mary J. Blige confirmed the nuptials to thousands of cheering hip-hop fans in North Carolina on Saturday.

“Congratulations to my man, Jay-Z, and my girl, B,” Blige told the crowd, dedicating her song “You’re All I Need” to the couple.

Rumors say the couple plan a coming-out party this week. On Friday, a swarm of media camped outside the building was in a state of frenzy, snapping and shouting at any sport-utility vehicle that drove down the cobblestone street.

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

The couple, who have apparently been dating for six years, have never publicly acknowledged they are together. Knowles, 26, and Jay-Z, 38, whose real name is Shawn Carter, have collaborated on the songs “03 Bonnie and Clyde” and “Crazy in Love.”

It’s been a big week for the hip-hop mogul. On Thursday, concert promoter Live Nation Inc. said it was in talks with Jay-Z over a potential business deal. The Los Angeles-based company stopped short of confirming published reports that the deal would give Live Nation a stake in virtually every aspect of Jay-Z’s career and land him a potential windfall in excess of $100 million.

A person familiar with the negotiations between Live Nation and Jay-Z told the Associated Press that the proposed 10-year deal was worth about $150 million and would cover three albums.
