Rumors that Timberlake, 31, and Biel, 30, were on their way down the aisle began circulating Wednesday (October 17) when US Weekly reported that guests had been whisked away to southern Italy for a top-secret event.
The couple first went public with their relationship in 2007, and following a separation early in 2011, Timberlake proposed to Biel during a Montana vacation in December of that year. Biel was spotted shopping at a Parisian bridal boutique earlier this month, and Timberlake reportedly ventured to Las Vegas and Mexico with friend for his bachelor party in September.
Stars like Andy Samberg, Timbaland and Biel's "7th Heaven" costar Beverly Mitchell have been photographed this week in Italy, celebrating with the newlyweds on Wednesday and Thursday.
Music Hook-Ups and Break-Ups
It's been six years since the former 'NSync frontman released a new album -- his newest set, "FutureSex/LoveSounds," dropped in Sept. 2006. He has since starred in several films, including "The Social Network," "Friends With Benefits" and "Bad Teacher." Most recently, Timberlake appeared in baseball drama "The Trouble with the Curve" alongside Clint Eastwood and Amy Adams.
During a recent interview for his new film, Timberlake said that when (or if) he returns to music, he won't be able to "pump" out albums and singles as quickly as many of today's top artists do. "For me, personally, when I do sit down and decide to do it, it's just a special thing," he said. The experience of making an album is "a really big deal," Timberlake added.
