The happy couple have been celebrating in Italy along with close friends Andy Samberg, Timbaland and 7th Heaven‘s Beverly Mitchell in advance of their weekend wedding.
According to multiple reports and published photos, on Thursday, Timberlake and Biel hosted a party where guests hung out around open fires and dined on fresh-made cheese, local olives and wine.
Shots of the occasion snapped by Splash News show guests (including former SNL star Samberg) lounging outside on white furniture. According to E! Online, the pair were both casually dressed – Biel in pants and a beige top, and Timberlake in blue pants, a white shirt and a skinny tie.
The night before, the group headed to a beach for a party complete with fireworks and live music.
The Italian celebration comes just weeks after Timberlake enjoyed a bachelor bash in Las Vegas and Cabo San Lucas.
The stars have been together for almost five years, though they split briefly in March 2011. They were spotted together again that September during a trip to Steamboat Springs, Colo., and soon reunited.
