Tiffani Thiessen Jokes She's 'Over the Hill' While Posing in Just a Towel for 50th Birthday

The 'Saved by the Bell' star kicked off her birthday with a joke and a nearly-nude photo shoot

Tiffani Thiessen is officially 50 and she’s (almost) baring it all.

The actress kicked off her birthday on Tuesday with a solo shot on Instagram as she proudly declared that she’s “over the hill” as she reached the milestone year.

“#thisis50,” she wrote in the caption of the photo, which saw her posing on a bed with only a white bed sheet wrapped around her body, which she held up with her arm around her chest. Half of her face is covered by her long brunette locks as she stares into the camera for the stunning shot.

Fellow stars filled the comments with love and support for Thiessen on her birthday, as her Saved by the Bell castmate Mario Lopez wrote, “Welcome to the 5th level kid!” and Sarah Michelle Gellar praised, “Looks pretty 🔥🔥🔥 to me.”

“Well done. Starting the 50s exactly right. Happy Birthday!!!,” Jenna Fischer commented.

Jennifer Love Hewitt also weighed in and shared a particularly heartfelt note in the comments. “Happy Birthday! I remember knowing you as a teenager and hoping to be as gorgeous as you one day! And I still feel the same! You make 50 look great! ❤️"

In the months leading up to her 50th birthday, the Beverly Hills, 90210 star opened up on The Jennifer Hudson Show about how she’s learned to "be happy" with every part of herself — including "the wrinkles that I've earned."

"I can’t believe it. I actually really cannot believe it. I cannot believe I’m going to be turning 50 very soon," she told host Jennifer Hudson of the milestone birthday. "I feel great. I actually feel more settled than I did in my 40s. Turning 40 was a bigger deal. I’m like, 'Ooh, I’m going to be 50!' I still can’t believe it."

"I say earned because I think I’ve earned them," Thiessen added. "They’re from all the tears and laughter — both! And I’m happy about that."

She also previously reflected on age while ruminating about how young she was when she started Saved by the Bell at 15 — and how she spent her teenage years in front of a camera, which was “kind of crazy.”

At the time, she told dietitian Shira Barlow on her podcast Good Instincts that she felt the “added pressure of what people were saying” about her appearance. But now as she ages, “I think people will say things, you know, and maybe expect me to look a certain way, yes, but I mean, it’s just not realistic. I can only age the way I’m going to age, right?”

“I’m the best I can be and I’m taking care of myself and doing things that I know will benefit the outside exterior of myself that people are seeing," Thiessen continued. "But yeah, those people don’t know what’s happening on the inside, right? Because that’s what actually helps the outside.”
