Update, 4:00 p.m.: Lady Gaga claims she knows the difference between Mariachis and a float full of scantily clad men.

An Instagram post from the singer suggested that she thought a massive gathering at Chicago’s Millennium Park was a Gay Pride parade when, in fact, it was the the Chicago Mariachi and Folklórico Festival.

“I am proud in general and did not mistake anything I spent the entire day riding around the city seeing people celebrate,” Gaga said in a response to Time magazine.

Lady Gaga got her social calendar mixed up on Sunday in the Windy City, mistaking the Chicago Mariachi and Folklórico Festival for a Gay Pride parade.

Likely visiting her fiance Taylor Kinney filming on location for “Chicago Fire,” Gaga noted a large gathering at Millennium Parl’s Jay Pritzker Pavilion from her balcony.

“Watching over Chicago Pride from my apartment and smiling so big. So many happy people. Happy pride!! #lovewins” she uploaded, with the word “Gay Pride” scrawled in red across her chest.

Except pride celebrations were raging all weekend on Chicago’s North Side, with attendance compounded thanks to Friday’s Supreme Court ruling that gay couples across the country have the constitutional right to marry in every state.

Not to be outdone, the Mariachi Heritage Foundation seized the opportunity to welcome Gaga into the fold by Photoshopping a sombrero on top of her head and adding superimposing “Mariachi Pride” onto her chest.

Gaga is currently in production on “American Horror Story: Hotel,” the fifth season of the FX anthology costarring Matt Bomer, Kathy Bates, Angela Bassett, Sarah Paulson and Finn Wittrock.

She’s also rumored to be writing a follow-up album to 2013’s “Artpop,” with an early collaborator in producer RedOne — and presumably a convention full of Mariachi’s ready to play backup.
