Camila Cabello and Shawn Mendes shared their talents in a living room performance [1] for the One World: Together at Home [2] global broadcast event, and their duet has Lady Gaga [3]'s approval. On Saturday, the couple sang a beautiful cover of jazz classic "What a Wonderful World" with Mendes at the piano. Gaga, who was integral in organizing the event, couldn't help but gush over their rendition as she watched it live at home. "I love you two so much, you're beautiful!" she said on her Instagram Stories.

Gaga opened the event with a cover of Charlie Chaplin's "Smile." [4] The night also featured at-home performances from artists like Jennifer Lopez [5] and Kacey Musgraves [6]. Each performer honored healthcare workers on the front lines of the COVID-19 pandemic in their own way. Watch Cabello and Mendes's touching tribute above.
