Justin Timberlake And Jessica Biel are to get married this week in Italy at a glamorous and star-studded ceremony, US Weekly reports.

Rumours had been rife about the upcoming nuptials of Timberlake and Biel, who sound more like a 70's crime fighting duo than a A-list couple, but they are an A-list couple and they're getting married soon so we'll shut up. The couple threw a casual pre-wedding party on Wednesday in Puglia, Italy, at the Cala Masciola beach on the Adriatic Sea, as you do. Guests included comedian Andy Samberg, who co-starred with Timberlake in an Emmy-winning "Saturday Night Live" digital short and the film "Friends With Benefits," a romantic comedy. This is the first wedding for singer-actor Timberlake, 31, since his high profile dating relationships with Britney Spears and Cameron Diaz didn't turn into wedding bells. And it's same for actress Biel, 30. They announced their engagement at the beginning of this year.

"Most celebrities do a wedding in their home country first, to make it official, and then they have a symbolic ceremony in Italy afterward, so they file no paperwork in Italy," Italian wedding specialist Diana Sorensen, owner of Sugokuii Events told E! "Personally, with Justin Timberlake and Jessica Biel, I do not feel they will have a legal ceremony in Italy. My feeling is that, like most celebrities, they've already done something in the United States."
