Kanye West is allegedly upset after Kim Kardashian's unairbrushed photos of her butt hit the Internet in April during a vacation in Mexico with a group of female friends. The reality star had lost 100,000 followers on Instagram following the incident.

A source told Radar Online: "He was just as humiliated and pissed off as Kim about those pictures."

"Kanye's worked his own butt off trying to cast the perfect image of them and she's blown it. He can't believe the state of it and this time — for the first time ever — he's behind her getting her butt fixed," the insider shared.

"Kim's already booked in for a string of repairs, including more fat transfer, lipo contouring, cellulite lasers and fillers," the source continued.

The rapper is known to be very cautious about Kardashian's public image. In 2012, West made headlines after he changed the selfie queen's wardrobe - her signature skin-tight, party girl attire was replaced by more sophisticated high-end wear.

During an interview with CNN style, Kardashian praised West's fashion. She said: "I really think that my relationship with my husband Kanye really changed everything. I mean, back in the day I thought I had the best style. I look back at outfits and I'm, like, mortified."

"I love my husband's opinion, so I always ask his opinion on everything and he always helps me put together my looks," she added. "Kanye sees my body obviously every day, so he can understand what works well on my body type, so it's been really fun to dress and we try things that work and some things that don't work."
