Blake Lively thought she was being funny with an Instagram post, but a lot of people aren't laughing.

On May 17, the expectant mother shared a split photo of herself on Instagram while donning an elegant gold Atelier Versace dress. One of the images showed her from the front, looking stunning, her baby bump just starting to show. The other image of the split showed her from the back, showing off her derrière.

L.A. face with an Oakland booty

"L.A. face with an Oakland booty," she captioned the side by side post of her on a Cannes red carpet, where she has been effectively owning the film festival in the South of France.

The post has enraged many of her 8 million Instagram followers (and many others), as they felt that she is toeing the line of racism.

To be fair, some fans found the humor in Blake quoting lyrics from Sir Mix-a-Lot's 1992 curvy-girl anthem "Baby Got Back," in which he fondly raps about a woman's backside. Others, though, felt she was being intensive and they filled her Instagram with their displeasure.

"Unbelievably problematic," one person commented, "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---."

Another said Blake's caption "is pure racism and sadly no white folks will ever understand that. Nice bodies have no geographical nor ethnic limitations. She should be ashamed of herself and how much do you want to bet she's never stepped foot in Oakland in her privileged life?"

Again, though, some thought it was humorous and many defended her.

"She's pregnant people. Carrying a baby 1. Adds weight. 2. Widens your hips. 3. It's her second one. Chill the f out. She's not trying to be anything but Blake. And since when is it a BAD THING FOR A WOMAN TO BE PROUD OF HER CURVES!!!!!!!!!!!"

Blake hasn't responded to the criticism.
