Kim's naked pictures were a big F you to the world!' - Khloe Kardashian

Her sister attempted to 'break the Internet' with a naked photo shoot for Paper magazine.

And now Khloe Kardashian is defending the risqué spread by claiming Kim was trying to send a strong message.

In an interview with E!, the 30-year-old believes her sibling was 'saying a big F you to the world' after being judged harshly while pregnant with daughter North West.

'People were just so hard on her during her pregnancy, that I think she feels so liberated to show everyone "Look how bomb I look!,"' she said of the mother of one.

Adding: 'So I kind of love that she's saying a big F you to the world.'

Khloe also revealed husband Kanye West was very involved with the full frontal pics by adding: 'It's something they both agreed to as a couple.'
