Kesha and Alice Cooper Pair Up for ‘School’s Out’ Oslo Performance

On Tuesday, Kesha teamed up with Alice Cooper for a rendition of the rocker's anthemic hit ‘School’s Out' while performing in Oslo, Norway.

At first, the pop star kicked off the song solo, but after the first chorus, she was joined by the 63-year-old legend. “Alice f—ing Cooper,” Kesha announced before getting down on her knees and bowing to the iconic singer.

After the show, the 24-year-old tweeted to the Rock and Roll Hall of famer, affectionately referring to him as "dad." She wrote, “Thanx for coming to Oslo to do SCHOOLS OUT with me dad… ; ) LEGEND. F—ING LEGEND.”

Cooper, who was in Oslo for his own show at Telenor Arena, replied, “Thanks @keshasuxx! Next time our stage, and be sure to bring some bandaids…” Fatherly advice, for sure.

'School's Out' became Cooper's first major hit song, peaking at No. 7 on the Billboard Hot 100 Pop Singles chart. The popularity of the tune helped put the 1972 album of the same name at No. 2 on the Billboard 200 Pop Albums chart.

Kesha will wrap her European dates next week and have a few days of rest before kicking off her extended North American Get $leazy tour, beginning on July 26 in Harrington, Del.
