Justin Bieber and Tiffani Thiessen Show Each Other Some Love.

This is one instance of cross-generational love that we fully support. After Justin Bieber sported a t-shirt emblazoned with Tiffani Thiessen's iconic role as the sultry and spunky Kelly Kapowski at Canada's MuchMusic Awards, Thiessen has returned the favor.

Forget wearing your heart on your sleeve, these two mutual supporters are wearing theirs across their chests, showing much love for their fellow -- save the 20 year age gap -- teen icons.

"Ha, thx for the love @justinbieber," Thiessentweeted after catching a peek of her 'Saved by the Bell' days -- sporting high-waisted jeans, suspenders and not much else -- remembered on Bieber's t-shirt.
Is Bieber the Zach Morris of the new teeny bopper generation? And if so, would that make Selena Gomez the Ms. Kapowski of the new era?
