We couldn’t fool you guys! 78 percent of voters correctly chose 38-year-old Joyce Giraud as the youngest gal to be featured on the show. Not only is Joyce a two-time Miss Puerto Rico, but she was a runner up at Miss Universe in 1998 — so it’s no surprise that this newbie still looks fab.

Coming in second was 41-year-old Brandi Glanville, who snagged 19 percent of the vote. Shockingly enough, Brandi is older than the lady who came in last place, Carlton Gebbia. Carlton, who scored only 3 percent of the vote, is only 40! Can you believe it?
