The 36-year-old actress said she is not against people going for plastic surgery to enhance their looks, reported Contactmusic.
"Whatever helps a person feel beautiful and confident is fine with me. I personally am afraid of the procedures that involve anaesthetic but ask me again in twenty years," Jones said.
The actress said she took her mother's advice on beauty.
"She (my mother) always told me that if I kept making so many weird and ugly faces my face would eventually freeze that way. Luckily I found a job where funny and/or frozen faces are encouraged," she said.
