Kardashian Kurse! Family's Brand 'A Sinking Ship' & Kanye West's 'Popularity Plunging,' Say Experts

Kim Kardashian and Kanye West are a match made in marketing and PR hell, according to several experts.

"When putting two egotistical, self serving individuals together, you'll create a rather vile spark. And in times of economic hardship across the country, bragging about materialism is typically frowned upon," public relations expert Angie Meyer-Olszewski told Fox 411.

"The Kardashian brand is a sinking ship. Anybody who jumps on board will eventually fall. A successful celebrity in his own right, Kanye made a horrible strategic decision by engaging himself with Kim," she added.

West, who has compared himself to everyone from Nelson Mandela  to Michael Jackson and even Jesus, has seen his popularity implode since he hooked up with the Keeping Up with the Kardashians star.

As RadarOnline.com  reported, West's Q Scores -- the industry's rating system for a celebrity's popularity -- has dropped a stunning 66 percent in the last 18 months.

His The Yeezus Tour  has also been more than disappointing, with his show this week at the 19,000 seat Sprint Center in Kansas City drawing only 4,500 fans.

And Kim's reality show career appears to be winding down.

"We are often drawn to people who have an ego and confidence that is derived from their talent. But an empty ego, based on a fake self-inflated image and concept, creates an over powering sense of desperation and superficiality," human behavior expert Patrick Wanis bluntly told FOX411.
