Why were they taking shots at Selena though? Was she part of the show at one point?
No, it's something completely random the writers came up with. They wanted to do a joke, and somehow no one in the entirety of the team that made this show thought about how horribly wrong it could go
I feel bad for Selena, the writers serving FOTP's hatred for Selener Having said that, at least nobody here makes fun of her health.
At least her charity got something out of it.
