How's that happen? If it helps any, Tom, your behaviors offended and concerned me lately too. I'll have my bags packed and ready.

With Tom Cruise and Katie Holmes's nuptials merely days away, some of their high-profile pals hopped a plane to Italy on Wednesday, PEOPLE has learned.

Expected wedding guests, including Brooke Shields, Jada Pinkett Smith, and Jennifer Lopez and Marc Anthony, boarded a private jet Wednesday at Burbank Airport.

Other expected wedding attendees, Victoria and David Beckham, have a shorter distance to travel for the wedding - but are struggling with what gift to get for the bride and groom.

"David and Victoria are still scratching their heads as to what is the perfect present to give them," says a source close to the couple. "It's pretty damn hard finding the ideal gift for Tom and Katie."
