Jennifer Lopez angered fellow passengers on a private jet taking guests to Tom Cruise and Katie Holmes' wedding ceremony by claiming all the best seats for her party. Other celebrity passengers including Jada Pinkett Smith, Leah Remini and director Cameron Crowe were shocked when they boarded the luxury 757 to find Lopez had taken over.

A source tells Us Weekly, "Jennifer Lopez sent her assistant to secure seats by laying her belongings on all the best seats!"

The actress also flew her hairstylist, Ken Paves, to Rome and set him up at the posh Hotel Hassler to do her hair for the big day. The singer ruffled more feathers at a group dinner at the restaurant Nino on Thursday night by refusing to stick to the informal dress code.

The source adds, "The November 16 welcome dinner was supposed to be casual. But J.Lo, of course, wore a gown. So much for casual."

Lopez also asked a waiter to prepare two "doggie bags" in the wee hours after the wedding, at 2:33 am, for her and husband Marc Anthony as they made their way to the airport to return to the United States.
