Glamour magazine’s latest special issue was supposed to be a source of inspiration for, and celebration of, body positivity and equality. Instead, it’s facing major backlash from one of the celebs featured on its cover, Amy Schumer.

The comedian’s name appears on the cover along with Adele, Ashley Graham, and Melissa McCarthy, as one of the “women who inspire us.” Schumer -- who previously covered Glamour's August 2015 issue -- was apparently disappointed that the mag implied she was “plus-size,” and that she wasn’t told prior to publication that she’d be included in the package.

“I think there's nothing wrong with being plus size,” she wrote on Instagram, along with a photo of her name on the cover. “Beautiful healthy women. Plus size is considered size 16 in America. I go between a size 6 and an 8. @glamourmag put me in their plus size only issue without asking or letting me know and it doesn't feel right to me. Young girls seeing my body type thinking that is plus size? What are your thoughts? Mine are not cool glamour not glamourous.”

Her message was met with mixed reactions. Some fans agreed that the label “plus-size” is demeaning, while others criticized Schumer for claiming there’s nothing wrong with being plus-size before going on to distance herself from it.

The mag’s special edition, dubbed “Chic At Any Size,” is billed as "created specifically for women with curves,” and is targeted toward women sizes 12 and up. According to Fashionista, it was created in partnership with Lane Bryant (a store where, ironically, sizes start at 14). Quoting a rep for the magazine, Fashionista describes the effort as “a curated and original editorial product presented by Lane Bryant.” In other words, this isn’t Glamour magazine proper... but it still has the mag’s name attached to it.

Glamour’s editor-in-chief, Cindi Leive, later posted a multi-tweet explanation, in which she apologized to Schumer for implying that she’s plus-size. However, Leive went on to defend the mag’s choice to include Schumer in its special edition, saying she hoped the comedian’s body positivity would be inspiring to readers.

Schumer wrapped up the conversation with another Instagram post on Tuesday afternoon: a video of her running along on the beach in a black bikini, pulling a kite. “Thanks for your thoughts to the people who didn't tell me how I ‘should feel,’” she captioned the vid. “Bottom line seems to be that these labels are unnecessary and reserved for women #muchlove.”
