Tiffani Thiessen

Beverly Hills, 90210 went off the air 17 years ago this month.

Which makes us feel VERY old to be perfectly honest.

As far as we know, Tiffani Thiessen and Mark-Paul Gosselaar did wake up this morning.

And we'd imagine that an alarm did give out a warning to both stars.

When the cast of Saved By the Bell reunited on The Tonight Show back in February, the sight of a very-pregnant Tiffani Thiessen as head cheerleader Kelly Kapowski drew a lot of laughs.

Now, that same Bayside bump has resulted in a second bundle of joy for Thiessen and husband Brady Smith.

Becoming a child star is like flipping a coin. There are only two ways it can turn out and there total opposites of one another.

You either turn into a washed-up tabloid trainwreck (See: Lindsay Lohan, any actor named Corey) or you blossom into an attractive, talented star who kicks ass well into adulthood (See: all the women in the list below).

Remember when Kim Kardashian was actually good friends with Paris Hilton?

What about when The Hills were alive with the sounds of laughter between Lauren Conrad and Heidi Montag? 

It's alright, cause we've got a Saved By the Bell cast mini-reunion photo of sorts between Tiffani Thiessen and Mario Lopez, thanks to the latter's Instagram!

First there were Saturday morning cartoons. Then we met Zach Morris and his brick of a cell phone and it was sayonara She-Ra! Hello, high school!

We rooted for Zach and Kelly to end up together and we cheered when they did. We watched Jesse Spano turn A.C. Slater into more than just a jock. We were there for Screech's first kiss.

Chris Paul and his Los Angeles Clippers may have lost in the Western Conference semifinals this spring.

But the All-Star point guard was given every reason to smile this week, thanks to a birthday gift that left him gushing online.

There once was a time when future heart throbs were a little dorky, would-be supermodels a tad awkward, and even the Kardashians were just regular kids.

Heck, even Justin Bieber was a kid once ... instead of a punk a$$ kid.

Note to all fans of Saved by the Bell: you may soon need a new pair of pants.

Tiffani Thiessen - who also starred on Beverly Hills 90210 and currently plays a role on White Collar, but who will remain Kelly Kapowski forever in the eyes of many - poses below for Me In My Place and looks rather attractive while doing so.

We recently reported about how Dancing With the Stars producers are under pressure from ABC to cast actual celebrities and fewer D-listers such as Bristol Palin, Kate Gosselin and The Situation. Well, today they landed ...

Effing Snooki.

Look out, Selena Gomez. Tiffani Thiessen is coming for your man!

We kid, of course, but the actress made a funny statement at this week's premiere of Horrible Bosses, donning a Justin Bieber t-shirt in response to that singer's outfit at last weekend's MuchMusic Video Awards.
