Lady Gaga has been sued by a surfboard brand over her Mayhem logo.

Surfboard company Lost International has taken legal action against the pop star, accusing her of copying their logo for her latest album.

According to the lawsuit obtained by TMZ, the company is suing Gaga for trademark infringement, claiming they own the rights to Mayhem as they sell merchandise and surfboards bearing the word.

Lost International maintains that it has been using a stylised version of the word on its products since 2015.

The company has accused Gaga, real name Stefani Germanotta, of using the logo in the same style on her album and merchandise without permission.

Elsewhere in the lawsuit, Lost International included a side-by-side image of one of its hoodies with the logo on the back and a hoodie from Gaga's merchandise collection with her version of the logo on the back to highlight the similarities.

The surfboard company also claims it contacted the Die With A Smile hitmaker and asked her to stop using the logo, but she didn't.

The lawsuit asks that Gaga be barred from using the logo and seeks damages, including any profits she made from using Mayhem.

Gaga has not yet responded to the lawsuit.

The Poker Face singer released the album on 7 March, marking her first full-length studio album since 2020's Chromatica.

The lawsuit comes as Gaga announced on Wednesday that she will embark on her first arena tour since 2018 this summer. The 32-date tour, titled The Mayhem Ball, will kick off in Las Vegas on 16 July.
