Kim Kardashian pours her generous curves into a swimsuit as she enjoys Hawaii vacation with Kanye West

Kim Kardashian's boyfriend Kanye West loves her curves so much that he has written a song in their honour.

And Kim showed just why her rapper lover is so besotted as she sunned herself in Hawaii yesterday.

In a picture she posted on Twitter the reality star can be seen with her back to the camera, all the better to showcase her curvy rear.

The 31-year-old turns her head and smiled at the camera in the shot, entitled 'Happy Sunday'.

Kim and Kanye are enjoying a luxurious vacation together, and have been seen hiking and visiting the grocery store in their Ferrari, all in matching outfits.

 Along with her swimsuit snap, Kim also posted a picture of herself in bed, pouting at the camera with a come hither face. She wrote 'night night' on the image.

The vacation comes as Kanye's rival 50 Cent insulted Kim with his cutting comments that 'One man’s trash is another man’s treasure.'

 The insult came as the rapper shared his thoughts on the The College Dropout's touching ode to his lover, the charmingly titled Perfect B****.

Kim herself has made it clear she is flattered by the song, written as a tribute to her curves.

According to TMZ, she has told friends 'I'm honored. I love it,' while clarifying, 'I know he doesn't mean it in a negative way when he says the word "b****."'

'The song talks about how he was with so many other girls but could never find the right one until he met me,' she said.
