Kim Kardashian most successful reality star

Socialite Kim Kardashian has emerged as the world's most successful reality TV star, with an income of $5.45 million in the past year.

Although the 29-year-old star makes a mere $400,000 from her TV show Keeping Up With The Kardashians, she makes more money from commercials, personal appearances and ads on her website, reported Daily Star online.

"She's not an actor and she is not a singer. But when you get the attention she does, you are worthy of being called a brand in your own right," said Ryan Schinman of Platinum Rye Entertainment, the US talent agency which revealed Kardashian's assets.

Kardashian, who was dating NFL footballer Reggie Bush until recently, was once paid $25,000 by Armani for writing a four-line Tweet that attracted 40,000 people to their fashion website in just 24 hours.
