The Girls Aloud singer isn`t against other people having cosmetic procedures but is adamant she wouldn`t agree to have an operation unless it was necessary for her health.
She said: "I would never go under anaesthetic for anything that wasn`t necessary.
"Plastic surgery is the patient`s choice - in most cases it`s not essential so perhaps it`s always the patient`s risk if it`s just for vanity."
Although Kimberley isn`t prepared to have cosmetic surgery, she does enjoy pampering herself and having beauty treatments.
The 28-year-old pop star and her bandmate Nicola Roberts treated themselves to a spa day at London`s exclusive Mandarin Oriental Hotel and Kimberley admits it felt great to be preened and spoiled.
She added in her column for Britain`s OK! magazine: "I`ve been pampered and polished this week! Nicola and I headed to the Mandarin Oriental in London for a spa day, which was amazing. We both went for a full-body, deep-tissue massage, which left me feeling totally relaxed. It was perfect!
"We had a proper catch-up in the sauna afterwards and then we headed to the hotel restaurant for dinner and a few glasses of wine."
