Kim Kardashian’s whirlwind blonde ambition tour across Paris has taken its toll on her locks, Breaking Celebrity News has exclusively learned. And although Kanye West’s fashion-forward wife is putting on a brave face for the flashing cameras, behind the scenes she’s proving that blondes may not have more fun after all.

“It’s starting to break off on some parts that are bleached,” a source told Radar.

And the 34-year-old reality star-turned-fashion muse is devastated about losing her famous hair.

“She feels like she’s going bald,” the source said. "She’s freaking out that it won’t grow back the same.”

After first taking a risk and cutting it short just weeks ago  Kardashian may now be paying the ultimate price for her hubby’s apparent attraction to bottle blondes.

“Kanye likes the blonde," North West’s mom said late last year. “But I think I’m going to stay dark.”

But for the naturally raven-haired reality star that was short-lived.
