PopUps: Oops! Gaga Confuses Chicago Mariachi Festival for Pride?

It's the thought that counts!

Lady Gaga made headlines this week after posting a picture to Instagram over the weekend that celebrated the Supreme Court's landmark ruling that legalized same-sex marriage in all 50 states.

In the photo, posted Sunday, Mother Monster is in her bra on the balcony of her Chicago apartment with the words "Gay Pride" written on her chest and stomach. She has her arms up in the air and is smiling over the city's Millennium Park.

But according to Jezebel, Chicago's gay pride wasn't taking place in Millennium Park -- it was the first annual Chicago Mariachi and Folklorico Festival. Pride was being celebrated in Chicago's North Side, on the same day, but a few miles away.

But the "Born This Way" singer denies she was confused over the two events and in a message to Time magazine on Twitter, Gaga cleared everything up.
