Kim Kardashian has begged a fan not to go under the knife.

The curvy socialite responded to a twitter message from a woman who claimed she was to undergo a head to toe plastic surgery transformation in the hope of saving her marriage by making herself look like the brunette beauty.

The fan wrote: "I'm getting head 2 toe plastic surgery nxt week 2 look like @kimkardashian so my husband won't leave me. He worships her (sic)".

But Kim, 29, begged the woman to change her mind, before sending a message to her over four million followers on the social networking site, imploring them to love themselves.

She tweeted: "Pls dont. Ur husband should love u 4 who u are! Don't try 2 b someone else. Im sure u are beautiful inside &out! Just as u are @brisajohnson

"Don't change yourself for anybody but yourself...be happy with who u are! Someone will appreciate and adore u just as you are. (sic)"

The reality television star recently admitted she had visited a doctor to discuss having her nose - which she sees as her "worst feature" - altered, but she decided not to go through with the procedure after seeing mock pictures of what she would look like.

She said: "But what's funny is about my nose, it's my biggest insecurity. I always want to get my nose done. I went to a doctor, I had them take the pictures, he showed me what it would look like and it just didn't- It- I wouldn't look the same."
