During a stop on her revival tour, Selena Gomez did something adorable. The Zumba-dancing internet sensation Audrey Nethery, who has a rare bone marrow disease called Diamond-Blackfan Anemia, got to shake a leg with the superstar. “Finally got to meet this sweetheart,” wrote Gomez in the video’s caption. “She owned it fully.” She had uploaded the video on Instagram and it is the cutest thing you’ll see today."Selena Gomez Dances With ADORABLE 6-Year-Old Fan"
