I used to think so, too. When we had a Dancing thread here at FR, someone said she should sue her plastic surgeon for a botched collagen job.
Then another FReeper said he/she grew up with Lisa and all her siblings and that’s the way her lips have always looked. Then, I kinda felt sorry for her. I still don’t like her, tho.
I don’t see how those lips could ever be called “natural” ~LOL
