Dolly Parton - I thought I would include Dolly Parton next, after Kenny Rogers. Dolly's obviously had a lot of work done over the years, too. Here are some funny quotes from her on the topic...
"I look just like the girls next door... if you happen to live next door to an amusement park."
"I modelled my looks on the town tramp."
"My husband said 'show me your boobs' and I had to pull up my skirt... so it was time to get them done!"
"You'd be surprised how much it costs to look this cheap!"
