Lisa Rinna of "The Real Housewives of Beverly Hills" and her husband Harry Hamlin participated in the #PuberMe challenge on social media, which brought awareness and raised funds for those affected by the hurricane devastation in Puerto Rico. Harry Hamlin is not just known for being Lisa Rinna's attractive husband on "The Real Housewives of Beverly Hills," but he is also a very well-known actor, known for his starring role on "Mad Men."

Hamlin proved that he has always had good looks and was blessed with attractive genes in a throwback black and white photo of him when he was younger.

The actor uploaded the photo to Twitter, using the hashtags #PuberMe and #PuertoRico.

The actor's wife Lisa Rinna shared an equally-old but more awkward photo of herself during her teenage years. The soap opera star had a haircut that was very telling of the times and wore a rainbow-striped shirt while chatting on a corded telephone. Despite all of the plastic surgery that Rinna has had over the years, a recognizable face still showed through in the old photo.

Lisa Rinna and Harry Hamlin have proven to be one of the "Real Housewives" fans' favorite couples on the show. They just celebrated their 20th wedding anniversary this year and have been together for 25.

They also have two beautiful daughters who are on their way to supermodel stardom that have been featured on the Bravo reality show occasionally.

Celebs post embarrassing photos for a good cause

A few days prior to the couple's tweets, the producer of "The Real Housewives," Andy Cohen uploaded his own flashback photo. Andy tweeted at Nick Kroll and Stephen Colbert to let them know that his puberty picture had outshined theirs.

The Bravo executive posted a picture of himself from his high school yearbook when he had dark, curly hair and big nerdy glasses in 1983.

Nick Kroll and Stephen Colbert initiated the #PuberMe challenge, asking celebrities to post photos of themselves and donate to help the hurricane victims.

Colbert also vowed that he would donate the sales of his Ben & Jerry's ice cream flavor to help the people of Puerto Rico, while Kroll will match the donations.

Fellow late-night talk show host, Jimmy Fallon, joined in on the fun, sharing a photo that looked like it was from the eighties.

"The Late Late Show's" host James Corden also posted a throwback photo of him from his early days in England.

Conan O'Brien could not let all of the other talk show hosts have all of the fun, so he shared a picture that he claims was from the day he "replaced David Letterman."
