LOS ANGELES, CA — In a revelation that has sent shockwaves through the entertainment industry, a multi-year research initiative has definitively concluded that celebrities, much like the general populace, experience birthdays annually and are, in fact, getting older.

The study, conducted by the Institute for Chronological Disparity Studies (ICDS), meticulously tracked the birth dates of hundreds of public figures, including recent subjects Queen Latifah and Matthew Broderick. The findings indicate a consistent pattern of aging, with participants observing their birth anniversaries on a yearly basis, often accompanied by social media posts and exclusive parties.

“For years, there’s been this underlying assumption, fueled by flawless red carpet appearances and suspiciously youthful complexions, that celebrities might operate on a different temporal plane,” stated lead researcher Dr. Evelyn Thorne. “Our data, however, unequivocally shows that even those with private jets and personal chefs are not immune to the inexorable passage of time. They just have better lighting.”

Industry insiders are reportedly scrambling to adjust marketing strategies. “This changes everything,” commented veteran publicist Brenda Sterling. “We can no longer rely on the public believing our clients are ageless demigods. We might actually have to acknowledge their 40s.”

The ICDS plans further research into whether celebrities also experience hangovers or struggle to assemble IKEA furniture.
