Wiz Khalifa Dissed at Barneys Shopping With Amber Rose

Wiz Khalifa may be topping the music charts, but apparently when it comes to the high-end fashion world, he has no pull.

Khalifa hit up Barneys New York in Beverly Hills, Calif., to do a little shopping with his girlfriend, Amber Rose, and his family members, but wasn't given the VIP treatment.

The Pittburgh, Penn., native dropped a cool $16,000 on women's shoes alone, but on-lookers said the staff treated him poorly. "After his spending spree on the shoes, Wiz went up to the ultra expensive men's department floor, but instead of rolling out the red carpet for him they refused to help the poor guy!" a source at the store told RadarOnline.com. "Not only did they fail to recognize him they actually thought that he was a thief and treated him like one! It was only when somebody pointed out to them who the guy actually was that they back-tracked somewhat."

Khalifa and Rose have been dating since the beginning of the year, and are already getting pretty serious. The lovebirds often gush over one another on Twitter and have opened up about their relationship in several interviews. Despite reports to the contrary, Khalifa maintains that there is no bad blood between he and Rose's ex-boyfriend, Kanye West.
