With the help of a xylophone, bongos and a kazoo, Adele belted out her hit song "Hello" on "The Tonight Show Starring Jimmy Fallon." Backing her up was host Fallon and "The Tonight Show" house band, The Roots, who all played school instruments.

Adele appeared on the late night show for the second night in a row and sung "Hello" effortlessly as The Roots and Fallon surrounded her with their kiddy instruments. Perhaps the best part of the entire musical performance was when the 27-year-old British singer popped out a plastic green flip phone during the chorus of the song.

When Adele visited "The Tonight Show" Monday night, she sat down for an interview with Fallon, played a game of "Box of Lies" and gave a stellar performance of her new song "Water Under the Bridge." While talking to Fallon, the singer revealed some of her favorite musical performers to be Rihanna and Frank Ocean, and that she could not wait for their new albums.

Last Friday, Adele released her highly anticipated third album "25," which was four years in the making. In slightly more than three days the album broke the single-week U.S. album sales record, as HNGN previously reported. "25" sold at least 2,433,000 copies in pure album sales to beat the previous record held by 90's boyband N*SYNC, who sold 2,416,000 copies of "No Strings Attached" in one week in 2000.
