Going to the chapel, and they're gonna get maa-arr-ried...

Some of the "few hundred" guests arrived near the Naples, Italy location superstars Justin Timberlake and Jessica Biel are set to wed at this week, and we've got the pics for you right here on Breaking Celebrity News.

The party, with guests such as Andy Samberg, formerly of Saturday Night Live, already started Tuesday and a fireworks show was held Wednesday.

An insider told the NY Post that Justin, 31, and Jessica, 30, chose the location because it “means a lot to both of them.”

"The maid of honor will be Jessica’s longtime best friend, Lindsay Ratowsky," a source told the paper. “Jessica’s stylist, Estee Stanley, who is also Justin’s partner in his home décor business HomeMint, has been helping to plan the wedding.

"A private plane was flown out of New York to take guests to Italy, including both their publicists. But the event has been shrouded in a lot of secrecy, and not even the guests were told the exact location or day of the wedding before they left.”
