Watch The Weeknd and Lauryn Hill Perform "In the Night" on 'Tonight Show'

The Weeknd and Hill were scheduled to perform “In the Night” together at the Grammys on Feb. 15, Recording Academy president Neil Portnow said.

After being a no-show at this year’s Grammy Awards, Lauryn Hill surprised fans by joining The Weeknd during his recent performance on The Tonight Show Starring Jimmy Fallon.

The 26-year-old singer later reflected on performing alongside Hill. "Most important experience of my life. Thank you Ms. Hill," he tweeted.

The Weeknd and Hill were scheduled to perform “In the Night” together at the Grammys on Feb. 15, Recording Academy president Neil Portnow said. But a rep from Hill's camp said organizers "announced a performance by Ms. Lauryn Hill prematurely and without approval."

The Weeknd still held his own with renditions of his hits "In the Night" — which peaked at No. 12 on the Billboard 200 — and his chart-topping smash "Can't Feel My Face."
