Jennifer Lopez Enjoys Dinner in Italy Without Ben Affleck

Jennifer Lopez continued her vacation in Italy without hubby Ben Affleck ... enjoying a Saturday dinner with a couple of friends at a swanky restaurant.

The singer/actress and her two pals – a man and a woman – arrived at the Ristorante Da Vincenzo in Positano for an upscale Italian feast last evening.

We're told Jen and Co. sat down at a table outside to celebrate a birthday for someone in the group. (In case you’re wondering, J Lo’s b’day is next month so it probably wasn’t her little soirée.)

Our sources say 2 security guards kept watch over the trio as they spent a few hours dining on yummy Italian dishes. J Lo, we're told, was in great spirits, smiling, laughing and chatting with her buds.

TMZ obtained a short video of J Lo's night out, showing her seated with her friends at the table surrounded by singing staff. J Lo was all dolled up and looked amazing as she took a bite of food from her fork.

Meanwhile, back in L.A., Ben has been riding around on his motorcycle with his son, Samuel , with J Lo nowhere in sight. In fact, Ben hasn't physically seen J Lo in a number of days – ever since she took off for Italy.

Before that, the couple was seen stepping out together to attend family events , while currently living apart in separate L.A. abodes. They're also trying to quietly sell their Beverly Hills home a year after buying it for $60 million.

What's more ... Jen has been spotted around town scoping out various properties for sale.

Of course, none of this is a good sign for their relationship.
