Justin Timberlake and Jessica Biel are reportedly set to tie the knot sometime this week in Italy.

According to reports the A-list couple will celebrate their wedding in the southern part of Italy this week. The couple who became engaged in December are believed to have kicked-off the celebrations with a huge fireworks display on Wednesday night.

A source close to the couple told Life & Style magazine: “The wedding is top-secret, hush-hush. Save-the-dates went out in the spring and little information was given. Guests were warned that any phones or cameras would be confiscated, so best to leave them at the hotel."

They added: “The wedding is so top secret, the invited guests are still in the dark about the exact venue! "They were told just to fly to Italy."
