Loris Karius's girlfriend had her own car spray-painted with the as part of a bizarre publicity stunt.
Last night, Sophia Thomalla posted a picture of her luxury car branded in white paint.
She captioned the snap with the words 'Na Klasse', which translates as 'no class'.
The model's photo saw her receive an outpouring of kind responses, slamming the apparent 'vandal's' behaviour.
German actress Pia Tillmann said: "What the hell is with people?" and South African dancer Motsi Mabuse simply wrote: "Really?"
However, in her most recent Instagram post, Sophia revealed that the spray-paint was part of a paid partnership with new Coca Cola water, Aquarius.
Sophia said: "Great idea of Aquarius! Mega idea! Mega campaign! Mega drink!
"We are all losers - of water and minerals! I still have to clean the c*** by myself ... Thanks for that!"
Karius is midway through a two-year loan deal with Besiktas, who paid Liverpool an initial fee of £2.25million.
It is not yet known how much Sophia was paid for the post.
