Billie Eilish is set to make a splash at the 2020 Oscars with her upcoming musical performance.

The 18-year-old singer announced on her Instagram Story that she will be performing during the In Memoriam segment of the annual awards show.

Though the singer made the announcement on Instagram, she did not state what song she would be performing.

The “Bad Guy” singer also turned heads with her red carpet attire — rocking a comfy Chanel suit while staying true to her oversized attire choices. The outfit is in stark contrast to the usual Gucci attire that she usually sports.

In January, Eilish made Grammy history by becoming the youngest artist ever to win album of the year for her chart-topping debut, “When We All Fall Asleep, Where Do We Go?" The record was previously set by Taylor Swift, who won the coveted golden statue at 20 years old for "Fearless" in 2010.
