Silicon In The City: Khloe Kardashian Debuts Plumped-Up Pout In New York -- Top Doc Says It's Injections!

Khloe Kardashian's giant fur coat drew stares in NYC on Monday, but her super-sized lips were just as distracting! And just like the faux fur garment, one expert says, her lips are not all-natural.

"It looks like Khloe has definitely had a recent plumping!" licensed aesthetician Alicia Hunter tells RadarOnline.com exclusively. "Most likely, it was Perlane or silicone. Her lips look amazingly full."

But because the big-boned Keeping Up with the Kardashians star has fuller features than her sisters, Hunter -- the author of The Accidental Diet: From Fugly to Fox -- says, "They actually fit her face. Although I think she is at maximum capacity!"

In the future, Hunter says, Khloe should lay off the fillers  because "She does not want to risk the dreaded 'trout pout,' especially in profile."

Khloe isn't the only Kardashian to go under the knife -- or needle. Kim has admitted to trying Botox, and Kourtney is proud of her boob job.

Half-sister Kendall Jenner also recently got her lips injected too, experts (who had not treated her) previously told Radar.
