The wedding of Justin Timberlake and Jessica Biel is nearing, but the celebration has already started.

On Oct. 17, Timberlake and his soon wife-to-be had a gathering of people for a pre-wedding party. The Wednesday pre-wedding dinner bash was held on the beach of Puglia located in southern Italy with over 50 guests in attendance.

Some of the party-goers included Andy Samberg, who Timberlake has worked with on Saturday Night Live and "The Lonely Island" crew to make viral hits such as "D-K in a Box." Also in attendance was music manager Johnny Wright, Timbaland and Biel's former "Seventh Heaven" co-star Beverly Mitchell.

The dinner party started around 8:30 p.m at the Cala Masciola beach that rests on the beautiful Adriatic Sea, where the couple has decided to hold their wedding ceremony within the week. Timberlake and Biel's guests enjoyed a fabulous dinner and rounds of cocktails while grooving to music such as Marvin Gaye's "Let's Get It On."

Guests enjoyed the beachfront decorations, which included various lanterns, and a wedding theme while the temperature stayed at a relatively brisk setting just perfect enough for some close mingling.

The celebration heated up as around 9:30 p.m., when the guests were shown a fireworks display that lasted about 10 minutes. As the night progressed, the guests returned to the Italian resort to relax the evening away.

The couple is reportedly excited about the upcoming ceremony, as an insider for Us Weekly stated "They are ready to get married!"

Thirty-one-year-old Timberlake and his 30-year-old bride are trying to keep the details and specific location of the wedding ceremony on a need-to-know basis for extra security.

According to USA Today, the couple has been engaged since December 2011, when Timberlake proposed to Biel with a six-carat bauble.
