Jack Black Slams Courtney Love Over Attack on Muppets' Nirvana Cover

The widow of Nirvana front man Kurt Cobain and the comedian who helped the Muppets cover the band's biggest song are at odds over the late singer’s legacy.

Love is upset about a cover of “Smells Like Teen Spirit” which appeared in last year’s The Muppets. Love told TMZ earlier this week that the Muppet version of the song "raped" the memory of her husband and that "Teen Spirit" had been used without her permission.

Jack Black, who appeared in the film’s cover of the song, disagreed with Love. He called her comments “absurd, absurd, absurd,” and presented his devotion to Cobain’s music as proof he would do nothing to disrespect the rocker’s legacy.

"I personally hold no one in higher esteem in the world of rock," Black told E! Online. "Kurt Cobain for me is at the top of the pyramid. He was the king…When he died it was sort of the end of rock."

Love’s assertion that Disney overstepped its bounds by including the song in the film has been questioned. Love reportedly sold off half of her remaining claim on Nirvana’s catalogue to Primary Wave Music, which has the right to license the band's music. In addition, former Nirvana drummer Dave Grohl appeared in the film, and he and former bassist Krist Novoselic gave his blessing for the song’s use.

Though Love may not have liked the barbershop quartet version of her husband’s biggest hit, she and her daughter with Cobain, Frances Bean, likely received profits from its use in the film.
