1. Zendaya Coleman

This Disney Channel star turned hip-hop artist is absolutely stunning. Not only is her music topping the charts, but she has already graced the stage of “Dancing With The Stars” and even won the Style Icon prize at this year’s Teen Choice Awards.

Predicted Age: 24

Actual Age: 18

2. Carly Rae Jepsen

"Hey, I just met you, and this is crazy, but [I’m almost 30 years old].” Yeah, I know. I was shocked, too.

Predicted Age: 18

Actual Age: 28

3. Joan Rivers

Joan Rivers may have gotten a lot of flack for undergoing so much surgery, but even the biggest critics have to admit that this queen of comedy did not look as old as she was.

Predicted Age: 67

Actual Age: 81

4. Sarah Hyland

Starring as a teenager in various roles including “Modern Family” and even a Disney Channel Original Movie, Sarah Hyland has given off a teenage vibe for years. With her innocent expression and a height of only 5’2, it’s easy to mistake her for someone a lot younger.

Predicted Age: 17

Actual Age: 23

5. Kylie Jenner

This one still baffles me. What with her clothes, makeup and edgy Instagram photos, I refuse to believe that Kylie Jenner is a teenager.

Predicted Age: 21

Actual Age: 17

6. Crystal Reed

Crystal Reed perfectly portrayed a teenage character on “Teen Wolf.” As a fan of the show, I can’t believe the onscreen heroine is closer to her 30s than she is to her teens. Sidenote: Rest In Peace, Allison Argent.

Predicted Age: 21

Actual Age: 29

7. Jennifer Lopez

I don’t know who J.Lo’s trainer is but I need to get in touch with him ASAP. Jennifer Lopez – who, might I add, just released a spicy new music video – seems to age backward and looks even more beautiful with each passing day. And apparently the men think so, too; her last boyfriend was 18 years her junior.

Predicted Age: 37

Actual Age: 45
