LOS ANGELES - Hearthrob actor-singer Justin Timberlake and actress Jessica Biel have tied the knot in southern Italy, they told People magazine Friday.

"It's great to be married, the ceremony was beautiful and it was so special to be surrounded by our family and friends," the couple told the celebrity bible in a statement.

Timberlake, 31 -- whose movie credits include 2010's "The Social Network" and "Friends with Benefits" last year -- and 30-year-old Biel have been dating for five years.

After splitting briefly and reuniting last year, the actor proposed to Biel in December in the dramatic surroundings of Big Sky, Montana.

They had kept details of their wedding under wraps, not revealing the exact location even to guests until the last minute, according to People, which said it will run details and exclusive photos in next week's print edition.

"She's a really, really, really special person," Timberlake recently said of Biel, the magazine reported.

Timberlake, chosen among Teen People Magazine's "21 Hottest Stars Under 21" in 1999 and most eligible bachelor in America in 2002, has previously dated Britney Spears from 1998-2002.

He has also been romantically linked in the past with Beyonce, Janet Jackson, Cameron Diaz and Scarlett Johansson.
