Kim Kardashian 'highest-paid Twitter user'

Kim Kardashian is the highest-paid celebrity Twitter user in the world, according to a recent survey.

The reality TV star is believed to earn around $10,000 (£6,250) per post on the micro-blogging service.

Kardashian was named top of a poll compiled by Ad.ly, an online service that allows celebrities and public figures the chance to "monetise" their tweets.

The 29-year-old socialite arranges endorsement deals through the company, which she then posts on to her 2.7 million followers.

She told Us Weekly: "I tweet about products, places, foods and fashion that I love."

Other celebrities currently using the online marketing service include Soulja Boy and Audrina Patridge.
