Julia Roberts
While not owning up to Botox, the Pretty Woman star (who has been voted as the world’s prettiest woman a record 11 times), has had surgery before. She famously had a nose job early on in her career. She has gone on the record saying that she has taken a big career risk in refusing to have a facelift.

Her reasons? “I want my kids to know when I’m pissed when I’m happy, and when I’m confused”, she told Elle magazine. That seems like a pretty good reason to us, but with skin like Roberts, who is the face of mega-brand Lancôme, why wouldn’t you be that confident?
