Of those making the trip: Biel's 7th Heaven costar Beverley Mitchell, who four years earlier had asked the actress to serve as a bridesmaid in her own Italian wedding, and Timberlake's frequent collaborators Timbaland, Andy Samberg and Jimmy Fallon. The then-future Tonight Show host even joined in during Timberlake's toast, cracking jokes with the singer in "a moment that everyone there will remember forever," Timberlake wrote in tribute of his good friend.
