When Prince agreed to appear on an episode of Zooey Deschanel's 'New Girl,' his one condition was that all Kardashian cameos be cut from the show.

In the Prince episode, the plot revolved around a party at Prince's house.

Deschanel recently revealed to Conan O'Brien that she had nothing to do with casting celebrities for the party scenes. But just before Prince was due to arrive, a PA rushed in and explained Prince's Kardashian ban.

He wanted all scripts and cameo scenes featuring Kris Jenner and Khloe Kardashian burned in a bonfire, to make sure there was no evidence they were ever involved.

Prince prevailed, the material was destroyed, and the episode was a huge success.

So, given the fact that Prince was a fan of New Girl and was willing to appear with other celebrities, why did he feel so strongly about the Kardashian-Jenners?

Let's explore the possible reasons he found them so toxic.

The most popular explanation being floated is that Prince was reacting to the time he invited Kim Kardashian on stage during a 2011 concert, and ended up booting her off in disgust when she wouldn't dance. The moment was such an embarrassment that Chris Rock was moved to comment ruefully on a late night chat show:

All that ass and she don't know how to shake it.

One can see his point; a gigantic waste.

But perhaps Prince's veto had more to do with sullying his reputation and 'brand.'

Widely revered as the coolest person alive, Prince was therefore an arbiter of cool. To appear with the reality TV stars might be seen as his endorsement of them. And Prince had exacting standards.

Guests to his Paisley Park home were not allowed to smoke, drink, or eat meat. Seen in this light, Kardashian-Jenners might be regarded as junk food.

Of course Prince could have afforded to be more magnanimous and given Khloe and Kris a break. But why violate his own principles for such an unworthy cause?

When a star like Prince or even Beyonce works hard to protect their mystique, proximity to a Kardashian would not only dull the glow of their magical aura, it would be tantamount to dumpster diving.

Let's just admit it. And let's say kudos to Prince for protecting his soul from the debasement of reality TV.

May He party forever like it's 1999, and may Kim learn to dance before waddling off this mortal coil.
