If it looks like a wedding, it must be a wedding, and that's what People and Us magazine reported Saturday by declaring powerhouse music couple Beyoncé Knowles and Jay-Z married.

Media were buzzing around the hip-hop mogul's New York penthouse in Tribeca on Friday.

Truckloads of white flowers and furniture were apparently spotted pulling into the apartment's garage earlier on Friday with celebs such as Gwyneth Paltrow and her husband, Chris Martin, also driving into the garage.

Towering silver candelabras stood guard on the street while a white tent was visible on the roof of the building, the Us magazine website reported.

Beyoncé, 25, and Jay-Z, 37, have been dodging marriage rumours for years.  Gossip websites went into a frenzy this week after it was reported the duo got a marriage licence on Tuesday in Scarsdale, N.Y.

People quotes a close friend as confirming the wedding, though neither side has sent out any official statements. The source said that Jay-Z, whose real name is Shawn Carter, "wanted it to be a really private affair" with close friends and family.

Others on the guest list included Beyoncé's mother, Tina, her father/manager, Matthew, sister Solange and fellow Destiny's Child members Kelly Rowland and Michelle Williams.

The couple, who have been together since 2002, reportedly arrived at 8 p.m. local time on Friday and the party went on until 3 a.m. Saturday.

Reports said an April 4 wedding makes sense since the pair are obsessed with the number 4. 

Beyoncé was born on Sept. 4 while Jay-Z's birthday lands on Dec. 4.  The rapper named his club 40/40, and the two also have matching "IV" tattoos on their ring fingers.
