Blake Lively may be the fashion queen of Cannes, but the Internet thinks she needs some serious pointers when flaunting that on social media.

On Tuesday, the Gossip Girl alum, 28 — who is pregnant with her second child — shared a photo from the festival’s red carpet. The side-by-side shot features the front and back of Lively rocking a curve-hugging gold sequined gown.

“L.A. face with an Oakland booty,” she wrote alongside the photo, quoting Sir Mix-a-Lot’s song “Baby Got Back."

While it seems the Los Angeles native was using the lyric to call out her voluptuous backside, thanks to baby No. 2, people were not having her attempt at humor. The picture has more than 16,000 comments (and counting), many of which call the caption racially insensitive.

"Another day, another rich white woman using [women of color’s] bodies as a punchline and commodity. As if Blake Lively wasn’t the worst already,” one user wrote.

“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,” another wrote.

This isn’t the first time Lively has stirred up controversy.

“I think the race issue started when she got married on a slave plantation. This just adds fuel to that fire,” an Instagram commenter pointed out.

While the actress received her fair share of hate for the caption, plenty of people came to her defense too.

“I sing this song at karaoke all the time. So, should I not sing it because I am not African American? I mean, I get what one side is saying about how black womens’ bodies and the stereotypes, etc. I really do get it, but isn’t this song celebrating a BIG BUTT!?” one user wrote.

“I’m BLACK and don’t see anything wrong relax people stop being so sensentive,” said another.

So what do you think … overreaction or is the hate on point?
