Justin Timberlake and girlfriend Jessica Biel looked more dreamy-eyed than ever as they attended a friend's wedding in Italy yesterday.

An uncharacteristically cheerful Jess played bridesmaid, clutching a bouquet and posing for pictures with the bride at the romantic ceremony.

The couple were attending the wedding of Jess' 7th Heaven co-star Beverly Mitchell and accountant Michael Cameron in the Italian city of Ravello.

A practice run for their own big day perhaps?

Jess and Justin certainly looked every inch the loved-up couple as they extended their trip to enjoy an idyllic break together in Rome.
