Kristin Cavallari, author of the forthcoming memoir Balancing in Heels, recently turned 29. Is she worried about getting older? Probably not.

“No one’s ever told me I needed to get a facelift or anything,” she told in 2011. “Never say never, but I don’t think I’ll ever get Botox because we don’t know the long-term side effects, and I just don’t think that can be good for you.”

Fair enough. It should be noted, however, that Kristin is also famously concerned with the alleged side effects of vaccines.

This has been 500 Days of Kristin.
