Buzz surrounding Justin Timberlake and Jessica Biel’s upcoming nuptials have them tying the knot any minute in Italy .

The rumor mill says the hush-hush event with invitations warning guests to leave cell phones and cameras back at the hotel, instructed guests to “just fly to Italy.”

Save-the-dates went out in the spring with very little info, and family members and guests who had to sign confidentiality agreements were not informed of the venue.

Jessica was recently spotted shopping in Paris during fashion week.
