"I answer to a higher power now," Timberlake, 31, joked during a recent press conference with the Hollywood Foreign Press of Biel, 30. "We have a couple of rules in our relationship. The first rule is that I make her feel like she's getting everything. The second rule is that I actually do let her have her way in everything. And, so far, it's working."
Here, Us Weekly offers a timeline of events that led to their Friday nuptials in southern, Italy and what has happened since the pair said "I do."

October 16: Kicking off their week-long wedding festivities on Tuesday, the couple flew some of their guests -- including music producer Timbaland -- into Germany, then whisked them to an undisclosed Italian location on private jets. "They took extra precautions and didn't tell anyone where they were going," a source tells the new issue of Us Weekly. Seconds a pal of the groom: "Justin wanted to be very slick with it!"
October 18: The night before Timberlake and Biel's nuptials, the couple mingled with causally dressed celeb pals including Andy Samberg, Biel's 7th Heaven costar Beverley Mitchell and music manager Johnny Wright during an outdoor cocktail reception.
