Dave Grohl team up with daughter Violet to cover Adele and Billie Eilish

"The voice of a fucking angel".

Dave Grohl has teamed up with daughter Violet to cover Adele once more, as well as debuting their own take on Billie Eilish.

On Thursday night, the Foo Fighters singer headlined the ‘‘Autism Speaks: Into the Blue’ gala in Beverly Hills.

After playing an acoustic rendition of ‘Everlong’, he was joined by Violet on Adele’s ‘When We Were Young’, after the pair previously performed the duet earlier this year.

But there was also time for a Billie Eilish cover too, with the pair performing ‘Idontwannabeyouanymore’.

Posting footage of the performance on Instagram, one fan claimed that Violet had “the voice of a fucking angel”.

As well as duetting with her dad, Violet joined Foo Fighters as a backing singer last summer too.

“That’s my boo!”, Grohl remarked after introducing Violet during a show in Toronto.

During another performance, he said: “Violet Grohl, you sound amazing!”

Meanwhile, Foo Fighters will headline their own CalJam festival this weekend – and it’s expected that it could see a Nirvana reunion take place.

Earlier this week, the rock giants posted two cryptic hints on Twitter that suggest a comeback performance could be on the cards.

The first came as they announced a screening of Joan Jett’s new documentary at the California festival. “CAN’T WAIT!! What else could we have up our sleeves???” Stay tuned….”, they wrote.

Jett, of course, famously joined Nirvana in 2014 as a backing singer for a one-time performance after their induction into the Rock and Roll Hall of Fame.
