Jessica Biel and Justin Timberlake's steamy clinch could have come straight out of one of his pop videos, but there was nothing staged about the unselfconscious moment.
The popstar gazed into 26-year-old Jessica's eyes as he held her face in his hands, while she wrapped her arms around him.
Justin Timberlake and his girlfriend actress Jessica Biel share a tender moment on vacation in Rome
The loving couple are enjoying an idyllic break together in Rome after a busy year in which Justin, 27, has unveiled his spring 2009 fashion line and written songs for Beyonce.
They have made the most of the late September sun, dressing casually in denim and leather jackets while exploring the city, heading hand-in-hand to all the tourist sites.
During their break, the couple shunned the expensive bars and restaurants favoured by celebrities in favour of low-key intimate drinking holes in the city.
The two seemed unaware of the passers by as they embraced in the Roman alley
One Irish holidaymaker couldn't believe her eyes when she spotted the A-list couple in one Roman bar.
She said: 'The bar was so tiny and quite cheap, so I couldn't believe it when my friend told me I was standing right beside Justin Timberlake. I had to do a double take.
'We asked him for a photo and he was very friendly and warm. He asked for time to finish his drink, but happily posed with us afterwards.
'Jessica looked so different in the flesh than she does on screen, she appeared very shy and normal and left Justin to do all the talking.'
