Selena Gomez showed up to the premiere of Disney's Frozen 2 with her adorable half-sister Gracie Teefey in tow Thursday (Nov. 7).
"Hope I'm officially the best big sissy ever now.. she was LIVING her best life!!" the star captioned a carousel of adorable photos of the pair on Instagram. "Frozen 2 was amazing!!!"
Walking the red carpet hand-in-hand, Gomez and the adorable six-year-old wore matching gray capes full of feathers and sequins over a pair of boho-chic dresses by Marc Jacobs. The singer -- whose comback single "Lose You To Love Me" currently sits at No. 1 on the Hot 100 -- accentuated her look with a pair of loosely-braided pigtails and Pandora jewelry.
