Kelly Kapowski & Justin Bieber The Tee Off

Four days after Justin Bieber wore a "Saved by the Bell" Kelly Kapowski t-shirt to an award show, Ms. Kapowski herself -- Tiffani Amber Thiessen -- returned the favor by wearing a Bieber shirt to a premiere in NYC last night.

Interestingly, Justin was born one year AFTER "Saved by the Bell" went off the air.
