Ready to feel old?

AARP Magazine -- the American Association of Retired Persons -- had a very famous face on the cover of its magazine this week, and social media was shocked to realize the actor was old enough to be considered a member of the seniors' group.

The celebrity joining the ranks of the organization for retired seniors? Luke Perry.

The actor, most famous for his role on "Beverly Hills 90210" as Dylan McKay turned half a century old on Oct. 11. The milestone birthday not only landed him on the cover of AARP magazine, but also garnered a pretty good play on his famous show's title.

"Welcome to the 902-5-OH" the magazine wrote underneath a picture of the hunk. Most people associate him with the famous high school based drama, which debuted back in 1990. It centered around students at Beverly Hills High, including Luke's Dylan. Though he played a high school student on the show, he was actually 24 years old when he joined the cast.

The role of Dylan launched him to stardom during that decade, and he became a major Hollywood heartthrob. Because of his '90s teen idol status, Luke's fans were usually accustomed to seeing him on the covers of magazines like "Teen Beat" and "Seventeen" -- not a magazine created to help enhance senior citizens' quality of life.

Naturally, once fans caught wind of Luke's latest cover social media was ablaze with denial. The revelation shocked one Twitter user to her core, as she tweeted, "Just saw Luke Perry on the cover of the AARP magazine in case they ask for my cause of death."

It forced "Beverly Hills 90210" fans to come to terms with their own current age, and most weren't pleased by the result.

"You just made a whole generation of people who thought they were still young very depressed," another Twitter user responded under AARP's cover unveiling.

One person on Twitter made an astute observation of another television character Luke now resembles -- the father from "Malcolm in the Middle," who was of course played by Bryan Cranston in the early '00s.

Hopefully Luke receives a free AARP membership for all of the unwanted attention brought to his age.
