Kanye West isn't doing so hot lately, and apparently the blame rests primarily on his 'Perfect Bitch.'

You knew this was coming: Kim Kardashian is reportedly tainting the temperamental rapper's image, and now it's hitting where it hurts the most: his wallet.

The New York Daily News reports that the relationship, which likely was at least in part dreamed up by their publicity teams, is negatively affecting West's already difficult reputation and, more importantly, his concert ticket sales.

The rapper's upcoming shows at Revel in Atlantic City are "not close to being sold out," according to an industry insider, and quite a few attendees walked out of his performance at the Hurricane Sandy 12-12-12 benefit concert. Dude, when people leave a charity show, that's not a good sign.

Apparently that night, Kardashian wasn't the only problem. It was also West's fashion sense. His kilt trumped even his own bombastic performance.

“Literally half the audience got up to go to the bathroom and it was the talk of the men’s room,” a source said.

“He has been meeting with top-level music executives seeking advice,” the insider added. “He’s not happy with the direction things have been going.” (Might we also suggest giving Ben Affleck a call? His experience as part of the couple known as Bennifer taught him a thing or six about how a relationship can almost torpedo a career.)

“His personal life is overpowering his music,” another industry source dished. “Every time he plays, people are wondering if Kim is going to be there. It’s not a good thing for him, especially if he wants to be taken seriously.”

Goodness knows no one takes West more seriously than West himself, so this has got to be pretty painful for him. Of course, it's hard to take a man wearing a leather kilt seriously, so he might want to look into, you know, wearing pants. And maybe not guest-starring on his girlfriend's faux-reality show so much.
