Selena Gomez Sings & Dances With Sister Gracie At Bestie Taylor Swift's Eras Tour Concert In L.A.

Selena Gomez is in her best friend era! The "Only Murders In The Building" star was spotted dancing the night away with her younger sister, Gracie at Taylor Swift's Eras Tour concert in L.A. on Tuesday. Selena posted a video of herself embracing the 10-year-old and swaying along to the songstress' hit, "Lover," on Instagram. She also shared a photo of her wrist full of friendship bracelets from the show and wrote, "Thank you to the fans that traded with me." The 31-year-old rocked a Taylor Swift Eras Tour sweatshirt for the fun night and posed with friends for a snap from the floor of SoFi Stadium. "Another one…" she captioned a selfie showing off the "Anti-Hero" singer's merch, seemingly pointing out that this is her and her little sis' second time seeing the performance. The pair also attended the Arlington, Texas event in April, where Taylor gave Gracie her hat while belting out "22."
