Justin Timberlake -- Married Man [PHOTO]

Sporting his new wedding ring, Justin Timberlake was spotted out in Fasano, Italy this morning ... after tying the knot with Jessica Biel yesterday.

Some of the famous peeps in attendance reportedly included JT's pals Andy Samberg and Timbaland, as well as Jessica's former "7th Heaven" co-star Beverly Mitchell.

The couple had been engaged since December after splitting for a brief time in 2011.

It's the first marriage for each, though Timberlake has been in several high profile relationships -- most notably with Cameron Diaz and Britney Spears.
