Fresh from her split with husband Marc Anthony, Jennifer Lopez, who turns 42 on Sunday, is living it up in Miami to celebrate her birthday.

On Saturday night, Lopez and her entourage of 16 – which included her mother, sister, manager and stylist – enjoyed a lavish dinner at Scott Conant’s restaurant, Scarpetta, inside the Fontainebleau hotel.

With a view of the ocean, the group indulged in a menu of authentic Italian dishes, including spaghetti with tomato and basil, foie gras ravioli and polenta.

“Jennifer looked radiant in a purple and silver evening dress,” a source tells PEOPLE. “And when they brought out her birthday cake after the meal, she began to sing. She was very happy. The whole group had a blast, staying for hours. They closed down the restaurant.”

Earlier in the day, Lopez worked up an appetite with a shopping spree, visiting the high-end boutiques at Bal Harbour Shops just north of South Beach. She bought several baby outfits for her 3-year-old twins, Emme and Max, at Bonpoint of Paris, and shopped at Hermes, Dolce & Gabbana, Valentino and Pucci.

On Friday night, after swimming in her condo pool with friends and family, including little Emme, Lopez and seven others enjoyed a pre-birthday dinner at the Wine Cellar of the Forge on Miami Beach, a favorite spot where she has dined with Anthony.

“Jennifer and her group arrived around 9 p.m. and went directly to the private wine cellar for a pre-birthday dinner,” a source tells PEOPLE. “It was very secluded and beautiful among the bottles with bold and vibrant labels. The meal was served on a long rectangle mirrored table with cloud-like chandeliers hanging above.”

According to the source, Lopez, who wore a long, brightly colored geometric patterned dress, was in great spirits. “She was chatty and charming,” the source says.

For a surprise, the Forge’s pastry chef created a special chocolate soufflé. It was presented to Lopez shortly after their meal, which started with appetizers of lobster peanut butter and jelly, a Forge specialty.

“Jennifer absolutely loved it,” the source tells PEOPLE. “When the waiters brought the soufflé, they sang ‘Happy Birthday’ to her while pouring everyone a crystal goblet of champagne.”
