Blake Lively unwittingly sparked outrage when she posted an Instagram photo from the Cannes Film Festival.
The "Cafe Society" actress posted a side-by-side picture of herself from the front and the back and quoted the song "Baby Got Back" by Sir Mix-a-lot.
"L.A. face with an Oakland booty," she captioned the image.
But the caption incited backlash from some fans, who called it racially insensitive.
"Unbelievably problematic, using women of color's bodies as a joke. I guess you just want people to know you're racist and you don't give a s**t," wrote on Instagram user.
