Dave Grohl's daughter Violet is working on her debut album

A source told The Hollywood Reporter: "She's a true torch singer.

"Her vocals are tremendous. She's very talented."

Violet made her music debut by teaming up with her rock star dad - who was Nirvana's drummer before forming Foo Fighters in 1995 - on a cover of 'Nausea' by punk legends X.

She also joined forces with David Bowie's pianist Mike Garson on a cover of the late music legend's 1970 classic 'The Man Who Sold The World', which grunge pioneers Nirvana covered in 1993 on 'MTV Unplugged'.

Violet launching her music career comes two months after Dave confessed to being unfaithful to his wife of 21 years - with whom he also has Harper, 15, and 10-year-old Ophelia - and dropped the bombshell news that he had welcomed a love child.

The 'Best of You' hitmaker - who tied the knot with Jordyn, 48, in 2003 - confessed on Instagram in October: "I've recently become the father of a new baby daughter, born outside of my marriage. I plan to be a loving and supportive parent to her.

"I love my wife and my children, and I am doing everything I can to regain their trust and earn their forgiveness."

The 55-year-old musician did not reveal the identity of his mistress or their child, and signed off his admission with by saying he and his family were "grateful" for the public's "consideration toward all the children involved" as they "move forward together".
