Scouting for wedding venues, perhaps?

On Tuesday, Justin Timberlake and fiancee Jessica Biel were photographed having a romantic dinner outside Naples, Italy. According to a source, the engaged couple first arrived in the southern Italian city, took a drive in the countryside - and stopped for pizza! -- and then enjoyed a two-day stay at a luxury hotel.

The singer-actor, 31, and actress, 30, then moved on to the quaint town of Bernalda, Italy and stayed at Palazzo Margherita. Owned by legendary director Francis Ford Coppola, the ancient villa-turned-resort was where his daughter, Sofia Coppola, wed Phoenix rocker Thomas Mars last August.

Although the locale as to be determined, the hot couple plan to tie the know "this summer at a private estate," one insider told Us Weekly. Timberlake proposed to Biel in late December in the mountains of Jackson, Wyoming.

Sans her husband-to-be, Biel was also spotted last week in Paris -- where she was spotted on a luxe shopping trip. Alas, the New Year's Eve actress reportedly did not pick out a wedding gown during her sojourn there, according to sources.
