Kelly Kapowski has Bieber fever -- and the feeling is mutual!

Justin Bieber rocked a T-shirt with a photo of Tiffani Thiessen in her Saved by the Bell days at Sunday's MuchMusic Video Awards in Toronto. Thiessen, 37, was clearly flattered by the 17-year-old's homage to her character! On Thursday, the actress showed up to a screening of Horrible Bosses in NYC wearing a Justin Bieber t-shirt.

"Thanks for the love, Justin Bieber," Thiessen tweeted Sunday night, along with a photo of Bieber on the red carpet with her face emblazoned on his chest.

"I'm just trying to show the love back [to Justin]," Thiessen told nymag.com of her own ensemble.

So is she a fan of the Canadian pop sensation? "Of course I am," she gushed. "he's adorable."

The White Collar star said her Bieber shirt was purchased in Times Square. "They're all over the place," she said . "I have, like, 9 million of them in my apartment right now. So if anybody wants Justin Bieber T-shirts, I've got them."
