Blake Lively has come under fire for racism after posting a controversial caption about her body on Instagram.

The 28-year-old star shared a split of two images from the Cafe Society premiere last week with the caption 'L.A face with an Oakland booty'.

Immediately the pregnant actress came under fire for being 'white and privileged' but using black women and culture 'as a punchline'.

Uh-oh: This is the photo caption that has landed Blake Lively in hot water

'Another day, another rich white woman using WOC's bodies as a punchline and commodity. As if Blake Lively wasn't the worst already,' read a post from @katbeee.

User @mindamaureen wrote: 'So much privilege even GOOP feels uncomfortable'

While @HellaBootsy questioned if the star had ever visited Oakland at all.

The blonde beauty was quoting lyrics from Sir Mix-a-Lot's 'Baby Got Back' but the defense did little to stem the tide of social media outrage.

'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', one follower wrote.

Another added: 'Used to like you Blake … turns out you appropriate black culture #unfollowed'.

The lyric refers to Oakland - an area of California considered traditionally black - compared to L.A.

The actress, who made her name in the hit TV show Gossip Girl, isn't the first star to use the lyric to describe a selfie online.

Khloe Kardashian and Katy Perry have both shared the same quote about themselves.

Khloe posted the comment alongside a selfie on Instagram nine months ago and didn't spark any accusations of racism.
