Katie Holmes was the one getting married on Saturday, but who was the biggest diva of the weekend? Jennifer Lopez! 
Tom Cruise and Holmes kindly arranged for a private plane to bring some of their more famous friends to Italy for their wedding. But a source tells Us Weekly that, hours before Jada Pinkett Smith, Leah Remini and Jerry Maguire director Cameron Crowe boarded the chartered 757 to Rome, “Jennifer Lopez sent her assistant to secure seats by laying her belongings on all the best seats!” Lopez also flew her hairstylist, Ken Pavés, into Rome and set him up at the posh Hotel Hassler to do her hair for the big day.
Meanwhile, it’s supposed to be the bride’s special weekend, but the singer made sure that all eyes were on her at a group dinner at the restaurant Nino on Thursday night. Says a source, “The November 16 welcome dinner was supposed to be casual. But J.Lo, of course, wore a gown. So much for casual.”
And the special treatment didn’t stop there. At 2:33 a.m. in the wee hours after the wedding, Lopez, 37, had a waiter sneak two doggie bags to her and husband Marc Anthony, 38, as they were on their way to the airport to return to the States.

It figures. Believe me, she didn’t tip the waiter, either.
