Keira Knightley had lip enhancement

I was browsing through blogs that contain information on celebrities with plastic surgery and I stumbled upon this blog. I never thought Keira Knightley underwent a cosmetic surgery makeover. According to the blog, she had lip enhancement. I searched for photos of her on the net and I noticed that there indeed is a difference in her lips in the old photos. Her lips were thinner then, but now her upper lip has gone quite bigger. 

However, I must say that if this news is true, then Keira did the right thing. Her looks have improved because of the cosmetic surgery makeover.
