She's clearly mad and this article is reaching.
I love Lady Gaga, and I'm not a fan of the recent weight jokes she's been getting, but is anyone really surprised? She's an ultra famous pop star, of course people will comment on her weight and looks. That piece is doing the most.
Gaga is unbothered and will probably starve/dance herself into a size -2 for ARTPOP promo next year and make us all EAT IT, perhaps literally. Or maybe she's settle down with Taylor for a bit and enjoy all her Italian cooking and munchies and pack on some girlfriend weight, whatever.
