`My pout is absolutely natural`

Washington: Kim Kardashian has brushed away rumours that she received filler injections in her lower lip, insisting her perfect pout is absolutely natural.

"Trust me, I`ve tried Botox on the show. I`m the first one to talk about anything that I do. It really pisses me off that all of these plastic surgery rumors are always linked to me," Usmagazine.com quoted her as telling Extra.

Still, the 30-year-old star admitted that her lips do look plumper as of late.

"I have the flu. I`m puffy and swollen, and I have no make-up on. Why would I just do my bottom lip?" she said.

Upon seeing herself in photos, Kardashian noticed that her "top lip was smaller and my bottom lip was huge. I`m thinking, ``That would be the worst doctor on earth to do one lip and not the other.``"

"It`s definitely something that I would never do," she said of getting filler injections again.

"I think my lips are big enough for my taste level," she added.
