Late night talk show host Jimmy Fallon, rap producer Timbaland and Biel's former "7th Heaven" co-star Beverly Mitchell were among those who celebrated the big day with the happy couple.
On Sunday, Justin and Jessica were spotted in an Italian airport, but no one got a glimpse of her wedding band. Justin, however, proudly displayed his.
Justin has been busy launching his new version of MySpace. He recently starred in "Trouble With The Curve" opposite Clint Eastwood and Amy Adams. He appears in the upcoming online gambling film "Runner Runner."
His wife stars in "Playing for Keeps" with Gerard Butler about a burnt-out soccer star who tries to win back his family but gets distracted by his wandering eye. She also appears in "Hitchcock."
