George Clooney and his human rights lawyer wife Amal Clooney invited family and close friends for dinner at Gatto Nero restaurant at Cernobbio on Lake Como, Italy, on Tuesday. Amal, 37, looked stylish in a sleeveless green dress. But it was her younger sister Tala Alamuddin who stole the show at the dinner.

The Clooneys are spending their summer at their private home near Lake Como. There were about a dozen people at the private dinner hosted by the famous couple, who are now planning to have a baby. The actor’s parents as well as Amal’s mother, Baria Alamuddin, were in attendance, according to E! News.

Tala stole the show in a bright red outfit. Her sizzling look consisted of an ensemble that featured one pant leg and a short skirt. The mother-of-one paired her look with a thick belt with leopard print.

The brunette beauty paired her dress with brown wedge high heel sandals. She carried a purple handbag that was in complete contrast to her dress. Her long tresses were left open with side part. She accessorized with some bracelets.

“Amal’s sister looked absolutely stunning. She stole the show,” an insider said. Meanwhile, Amal’s floral green dress is from Valentino’s Spring 2015 ready-to-wear collection.

The dress showed off her slender figure with cutout details at the waist. The midi length with its vintage green shade looked sophisticated. She accessorized with golden earrings and opted for dark red lipstick for her evening look.

George, 54, kept it casual in a short-sleeved, white shirt. The top buttons of the shirt were undone while he kept the shirt out. The actor sported a goatee for the family dinner.

His parents Nick and Nina Clooney and his older sister attended the dinner. The gathering was very down to earth, and sat with other diners though they required some privacy, the source said. The insider added that the restaurant was full, but when they came in, there was surprise and excitement.

The group had meatballs, prawns with fried bacon and risotto with asparagus and egg. George and Amal also shared a tagliata steak, the source added. Light wines including the special Ca’ Del Bosco Saten and Cremes Gaja went around for the celebratory night.
