Los Angeles, Aug 4 (IANS): Reality TV star Khloe Kardashian has undergone plastic surgery to achieve her new look, according to some celebrity plastic surgeons.

The "Keeping Up with the Kardashians" star has undergone a complete transformation since the reality show first aired, the doctors have said, reports radaronline.com.

“Overall, Khloe Kardashian looks different than she used to look. She appears to have had her nose thinned, possibly from a rhinoplasty,” said a doctor named Anthony Youn.

The news website further claimed that Khloe's lip looked "plumper" when she was photographed at airport here on Monday.

Youn said the 36-year-old may have gone under the knife to fix her nose, lips and chin.

"Her lips looked plumped, likely with injectable fillers like Juvederm. Her forehead and eyebrows also appear relaxed, possibly from injections of a neurotoxin like Botox," Youn added.

Beverly Hills plastic surgeon doctor Susan Evans said: “It appears Khloe's not going to be outdone by her luscious lipped little sister, (Kylie). Her lips look much plumper and fuller, most likely a hyaluronic acid. Her nose also looks straighter, possibly achieved surgically or non-surgically with calcium hydroxyapatite, filler to raise the nose bridge."

Khloe hasn't commented on the report yet.
