Happy 38th birthday to Angelina Jolie!

To celebrate her big day, which is today, a source tells ABC News that on Monday night, the actress and her fiancé Brad Pitt slipped away after the Paris premiere of his film "World War Z" to enjoy a romantic dinner at Il Vino-a restaurant that focuses on wine.

During the multi-course meal, which featured red and white wines, and a chef's choice of fish and meat, the couple looked "very relaxed."

"They loved the place," the source continued, adding that they chose the restaurant because of its focus on wine. "They had a very nice time."

While the big draw to the eatery may be the wine (after all, it's run by Enrico Bernardo, winner of the World's Best Sommelier award), the staff made sure to celebrate Jolie's birthday in a traditional way, and served a cake for dessert.

Earlier in the evening, Brad Pitt was reportedly asked on the red carpet if this birthday felt extra-special, in light of Jolie's recent double mastectomy.

"Every year is special," he said. "This year isn't any more special than other years. We're going to celebrate in the air with the kids because we're going on to [Berlin]."
