Tiffani Thiessen Wears Nothing But Bed Sheets for 50th Birthday Photo: 'Aging Like Fine Wine'

Tiffani Thiessen

Tiffani Thiessen is stripping down to a bare version of herself in honor of her birthday, and fans can't help but applaud the actress for how gracefully she's aged over the years.

In a new solo snapshot shared via Instagram on Tuesday, Jan. 23, the Saved by the Bell alum posed on a bed, seemingly only covering up with a sheet, as she welcomed her personal new year.

The sultry shot was taken on a tan-colored bedspread, with not much else visible in the photo aside from pillows situated against the tufted headboard. The actress wore a face of neutral beauty-enhancing makeup, while her hair was casually tousled to the side, covering one eye. Natural light poured into the room, making the scene a bright and fresh spot for the stripped-down vibe of the shoot.

"Over the hill. #thisis50," the image was captioned.

The picture, shared on Thiessen's birthday, saw a host of followers, fans and friends flooding into the comments section with sweet, celebratory notes for the mom of two on her special day.

"Looks pretty 🔥🔥🔥 to me," a top-liked comment dropped by her longtime friend and fellow actress, Sarah Michelle Geller, read. Nearly a decade ago in 2016, Gellar joked in a previous birthday message sent to her pal, "Wife, mother, chef, actress, hostess, and extremely beautiful. If I didn't like you so much, I might hate you," alongside a crying-laughing emoji.

One social media user noticed she was "50 & FAB!" while someone else penned, "#goalsfor50 😍😍😍 gorgeous! ❤️."

"If this is 50…. You are the poster child for beauty + grace, inside and out. Also… wowza! 🔥," a third added, as a fourth agreed, "You’ve set the bar very high. 🙌🔥," and a fifth said she was (obviously) "aging like fine wine," in part.

"Welcome to the 5th level kid!" Saved by the Bell costar Mario Lopez wrote.

An additional fan insisted she looks "Forever 29," and we don't disagree!
