The composers of her 1996 number five hit have accused the Canadian company Entertainment One of infringing their copyright over the song Peppa’s Party Time, which was released on Peppa Pig: My First Album last July.
After news of the legal case made headlines, Louise took to Twitter calling for “justice” for her track.
She tweeted a picture of herself from her pop heyday and said: ”Oink #JusticeForNaked,” along with a pig emoji.
Louise then shared a video of a Peppa Pig scene with Naked dubbed over the top of it, writing: “That naughty pig!@peppapig #JusticeForNaked.”
According to Metro, Entertainment One has since settled with producer Denis Ingoldsby and the song’s authors.
The Mirror claims that they could stand to make £1 million, as they are now entitled to all backdated and future royalties, while their names have also been added to the credits on Peppa’s track.
Louise has staged a return to music in recent months, and released her first album in 20 years last week.
Heavy Love charted at number 11 in Friday’s Official Chart.
The 45-year-old former Eternal singer addresses elements of her marriage and subsequent divorce from ex-husband Jamie Redknapp on the album.
On one song, Wrong, she describes how she felt trapped by their marriage, with lyrics including: “You said I don’t need them, you would lift me up. You were wrong.”
Later she sings: “I should have fixed it before it was unfixable.”
Addressing the line in an interview with The Sun’s Fabulous magazine, she said: “I’m saying it’s not all your fault and I should have dealt with things earlier.
“I’m not the kind of person that ever would be damning of anybody, and this album is very much about how I felt. It’s not meant to be mean or unkind.”
