London singer Ella Mai is currently blowing up on the strength of her sumptuous ’90s R&B throwback hit “Boo’d Up.” And last night, she took it to Jimmy Kimmel Live!, making her debut TV appearance by performing the song, minus its electronic Mustard beat, from a stage covered in blue fog. She seemed genuinely thrilled to be there, too, afterwards tweeting, “between kimmel and selling out almost all of my tour dates in like 3 hours, today is definitely one for the books! forever grateful.” Watch below.
