PRINCESS vibes: Selena Gomez spotted taking her sister Gracie, nine, along for celebratory dinner with her new besties Nicola Peltz and Brooklyn Beckham at LA

In true Selena Gomez style, she enjoyed her best friend Nicola Peltz’s birthday with her family on Saturday.

Casually chic: Selena Gomez, 30, and her sister Gracie, nine, look comfortably chic in coordinated outfits  as they arrive for an early birthday dinner with birthday girl and pal Nicola Peltz and her husband Brooklyn Beckham on Saturday in LA

Nicola, 30, brought her nine-year-old sister Gracie with her to dinner with Brooklyn Beckham and Nicola at Cecconi’s Restaurant in Los Angeles. Gracie is the other person in the picture.

Sisters: Explaining the post on social media, Selena wrote, 'It¿s not your bday yet but let¿s celebrate NOW!' to which Nicola replied, 'Omg my sisters!!'

The singer of ‘Calm Down’ wore a black Ferrari sweatshirt, black trousers with straight legs and zippers put unevenly on the legs and an old three-strand pearl necklace with a sterling silver or diamond clasp.

The actor from “Welcome to Chippendales” showed off her toned legs in blue and pink floral boots with cutouts on the sides. She put her dark hair up in a high bun and wore diamond earrings with it. 

Curves: Nicola, who will turn 28 on January 9, showed off her curves in a sheer black dress with an asymmetrical hem that began at her thigh and ended below her knees. Brooklyn, 23, kept his look simple, donning black pants and a white T-shirt

She has been married to Brooklyn Beckham for eight months. He wore black trousers and a white T-shirt to keep his look simple. He got ready for the cooler evening weather by bringing a black leather coat and tying a white jumper across his chest and under his arm in an uneven way. 

Inseparable: Selena and the Beckhams seem to have been inseparable since  Nicola hosted a listening party to celebrate the debut of Selena's documentary My Mind and Me in November

A picture of Gracie, Selena, and Nicola kissing on the cheek at the party shows how close the three have grown as friends in the past few months.
