Best Twitter reactions to Luke Perry's AARP magazine cover

AARP did a good job of making a whole lot of Beverly Hills 90210 fans feel very old by putting Luke Perry on the cover of the magazine's latest issue.

Yes, Dylan McKay is 50 and if finding that out doesn't make some fans of the former heartthrob feel old enough, AARP mag honored his milestone birthday by putting him on the cover to remind those fans that their youth is gone.

On Oct. 11, Twitter erupted with reactions from tons of 90210 fans when the cover was revealed. Here are some of the best reactions to the actor turning the big 5-0 and gracing the cover of the organization for retired people and seniors.

However, there is a silver lining in all this ... as one Twitter user pointed out, the actors on 90210 were not really teenagers when the show aired, they just played them on T.V.

Plus, Perry's co-star Ian Ziering is 52 and can still fight sharks and save the world, so maybe your fifties won't be so bad.
