“Just gonna leave this Christmas throwback right here for everyone around the world’s enjoyment… 4 yrs old. Teeth bucked and discolored. Rocking a perm,” wrote Dwayne Johnson on his Instagram account when posting a throwback picture. “And for the record, EVERYONE thought I was a little girl growing up. And clearly even at a very young age, I always had 'a way' with all the girls - mainly because they thought I was one. And thanks for the awesome haircut, mom.”

“Meet Alicia. At her home 'studio' on 137th St in Harlem. Just a simple one bedroom. The room was so small, she sat on the bed and played the keyboard piano trying to come up with songs that matched the feelings in her heart. She sang in a closet covered with blankets through blazing NY summers trying to find her voice and show the non-believers she could do it. No matter what they said. She could do it all,” Alicia Keys reminisced about herself as a teenager.

Reese Witherspoon took a nostalgic approach on her throwback Instagram caption: “POV: it's 1987. You got your cool new Benetton sweater. You memorized all the words to 'Heaven is a Place on Earth' by Belinda Carlyle. Gonna go to a roller skating birthday party this weekend and play Dragon Slayer at the arcade. Eat Whatchamacallits and drink Cherry Cokes. LIFE IS GOOD.”

Many try to speculate what procedures certain celebs have or have not done, whilst our beloved Hollywood stars are often happy to share the secrets of their never-ending youth. Some of these tips are not as extravagant as you might think, like eating healthy, getting a solid amount of rest, or never going to bed with a full face of makeup on.
