Well… there’s at least as much of a point in them paying it as in a random singer paying it
I am sure you’ve seen the infamous photo of the female team next to the male team; bikinis vs shorts and singlets. If a celebrity pays the fine, then the men in that picture are not paying it. They can just sit back and let the girls sort it out amongst themselves.
Don’t get me wrong, I am sure the female players appreciate Pink’s shout out, but the male players and male staff of the association need to literally put the money where their mouth is.
