BlackBerry CEO John Chen said he is not accepting any offers from "Keeping Up With The Kardashians" star Kim Kardashian.

In October, Kardashian made an unexpected appearance at a tech conference in California, where she called her BlackBerry Bold her "heart and soul," Daily Caller reported.

"People are horrified that I use a BlackBerry, but I'll never get rid of it. If you have to handle an email and you have to type fast, I need that board," Kardashian said. 

As suggested by the tech conference host, Kardashian said she might go to the smartphone company's corporate office in Waterloo to talk about serving as a spokesperson.

On the other hand, the company's CEO said he has no plans of making a deal with the 33-year-old reality star.

At a summit in Beijing, Chen said the smartphone company was focusing on its business users "who need to type, read large documents and email on their phone."

"I'm not into bringing celebrities on board," he added.

One of the "sharks" of ABC's entrepreneurial competition show "Shark Tank" Kevin O'Leary also commented on Kardashian's unsolicited promotion of BlackBerry.

"Right now, she can put BlackBerry on her credit card," O'Leary told Business News Network referring to Kardashian although he also commended BlackBerry for being a useful smartphone for professionals.   

Meanwhile, Kardashian is gracing the cover of the upcoming winter issue of Paper Magazine featuring a photo of her showing her butt.

North West's mother took to Instagram to share the photo, which received different reactions.  

Among those who commented on the racy photo was "Glee" star Naya Rivera.

"I normally don't.'re someone's mother...," wrote Rivera who recently got married to actor Ryan Dorsey after calling off her engagement to her "Sorry" collaborator Big Sean.

The photo was shot by French photographer Jean-Paul Goude, who has worked with Esquire, Perrier, Kodak and Chanel among others.

Also featured in Paper Magazine's winter issue is Goude's iconic "Champagne Incident" photo recreated by Kardashian.
