Billie Eilish Performs "I Love You" With Her Brother on SNL

Watch Billie Eilish's Heartwarming Performance of "I Love You" With Her Brother on SNL

After a four-month hiatus, Saturday Night Live is back, and Billie Eilish is already making me tear up with her heartfelt performance of her hit song "I Love You." Eilish's 22-year-old brother Finneas joined her on the stage, and the siblings wore matching outfits as they sang their hearts out in front of a twinkling, star-covered backdrop.

In addition to Finneas's gentle guitar strumming and the pair's angelic harmonization, Billie and Finneas also exchanged a few sweet smiles in between vocals, resulting in a heartwarmingly emotional performance. The best part? Finneas claps for Billie at the end and gives her the cutest proud big brother look. Aw! Watch the siblings' sweet performance in the video above!
